learn to smelt black iron ingot: learn it in the hall of Seven Sages in Blackstone abyss (the second NPC on the right hand). Materials required: 20 gold ingots, 10 real silver, 2 Ruby; The Blackstone abyss key (task) needs to be turned on and off. The key is to go through the Blackstone bar and ask the bar owner Prag to buy 6 bottles of black iron beer for NPC or complete the task of enchantment NPC

smelting black iron ingot: near the entrance of MC in the Blackstone abyss, there is a furnace guarded by fire elements

to make black iron equipment: you must use the anvil behind isendios in the black stone abyss

open an Olympic gate. Fly to the intersection of 10 characters. Turn the barren land around once. If you see copper ore, you can mine. If you can't mine tin ore, you should pay attention to the location. In barren land, three ponds - sweet water oasis + stagnant water oasis + forgetting pool, you will brush one copper ore or tin ore at a fixed point. Sometimes when you go to sweet water oasis, you will find four copper mines underwater...

practice tin ore to green in barren land It's difficult to make the tin mine green when it's barren. You can choose to switch to shizha mountains when you see the yellow tin mine. Shizha has more tin mines

after mining 125, you can go to mine iron ore. to qianzhenshilin, there are five major mines of gold, silver, copper, iron and tin = = |
or you can go to the barren land Let's go to the wasteland

when you can collect the secret silver, I suggest you fly to the thorn Valley, then to the sad swamp, and then to the curse land below. Has the map of the curse land been opened? In the northernmost part of the curse land, there is a LM camp watch fort. On the left of the watch fort, there is a cave. There are three high-grade silver mines, namely Mitsui, Saiyin and Zhenyin. Of course, the landlord can also consider going to Huanxing mountain to collect Saiyin.

OK. When you see that the fuser mine is no longer bright red, you can go to xlss, Dongquan and Dongwen, which are rich in fuser PVP preparation.

if there are thousands of horses, it only takes two days to practice mining to 300 at most. However, if the building owner has the impulse to go to the ruins for a long time, find a glove F + 5 mining. The heiyaoshi mine in the ruins needs 305 mining

4. That is the pull of online games. There's too much for you. There is a "professional life online games" earlier pull. Well written. It's recommended

5. Guide: ball mill is a very common grinding and mining equipment. Its grinding principle is to use the friction between the material and the steel ball or steel column and the rotation form of the rotating drum to make the material reach the ideal particle size standard, so as to facilitate the classification and flotation operation in the subsequent beneficiation process. Small series for you to introce the ball mill, then, as a central part of the ball mill grinding operation, whether there must be emphasis on the operation method? Here, Hongxing Machinery believes that as long as we master the nine word secret of high concentration, large return sand and uniform feeding, we can achieve the most ideal grinding effect. It will be described in detail below. The so-called high concentration mainly refers to the mass fraction (pulp mass fraction), which is the percentage of ore mass (dry weight) and total pulp mass (ore + water) in the pulp. Here, the mass fraction refers to the pulp mass fraction (grinding mass fraction) in the grinding machine. Grinding mass fraction is an important factor that affects the proctivity of grinding machine. It determines the friction between grinding medium and ground material, pulp fluidity and effective density (density difference between medium and pulp). In the operation of the grinding machine, a higher grinding mass fraction is generally used, so that a layer of slurry can be attached to the surface of the medium, so as to enhance the grinding effect beneficial to the grinding. At the same time, there is a large amount of ore per unit volume in ore discharge, so the ore discharge is large. However, if the pulp mass fraction is too high, e to the increase of pulp density, the effective density, activity ability and striking effect of grinding medium will be weakened. At the same time, e to the high mass fraction, high viscosity, poor fluidity and rection of total ore discharge, the proctivity of grinding machine will be reced and even swelling will occur. Therefore, high concentration means to increase the grinding mass fraction within a certain range, which is concive to improving the grinding effect. On the other hand, we need to realize large sand return in the process of ball mill operation. In order to explain such advantages, first of all, let's talk about what is sand returning. Return sand refers to the coarse-grained fraction returned by the classifier to the grinder for regrinding ring closed-circuit grinding. The amount of return ore is often several times of the original ore feeding. The ratio of return sand quantity to raw ore feeding quantity is called return sand ratio. Practice has proved that the return sand ratio will directly affect the proctivity of the mill. The larger return sand ratio increases the total feeding capacity of the mill, thus increasing the discharge speed of the mill, shortening the residence time of materials in the mill and speeding up the circulation. In addition, although the returned sand is coarse-grained ore, it is finer than the raw ore after all, so the total feed particle size composition of the mill becomes finer, and the comprehensive results are concive to improving the proctivity of the mill. The relationship between the return sand ratio and the relative proctivity of the mill was studied. It can be known that within a certain range (such as between 100% and 500%), with the increase of the return sand ratio, the proctivity of the mill will increase. When it reaches a certain value, the proctivity increase is very small, and the total feeding capacity of the mill is close to the maximum throughput, which is easy to cause ball mill swelling. Therefore, the sand return ratio should be kept stable and close to a constant value. Finally, in the process of ball mill grinding operation, we should also pay attention to the situation is the average feeding. Why do you say that? In fact, there are two main implications: one is that the feeding speed (ore quantity fed into the mill per unit time) is constant; The second is that the particle size composition of ore feed is uniform. In order to improve the grinding efficiency, the ore feed should be continuous, uniform and stable at a high level. More time and less time will make the mass fraction in the mill fluctuate frequently, which is not concive to the grinding process. Particle size segregation of grinding feed often occurs in the silo, the middle is fine, and the surrounding is coarse, which is easy to cause uneven feed composition. If the operation can not be adjusted in time according to the particle size, swelling will occur. Therefore, multi-point discharging and feeding should be adopted as far as possible. As long as you master the above ball mill operation specifications, or the experience and lessons learned by predecessors through personal practice, you can make the ball mill work in the best working condition all the time. The core problem revealed by the nine word secret is the balance of input and output efficiency.

Learn to smelt black iron ingot: learn it in the hall of Seven Sages in Blackstone abyss (the second NPC on the right hand). Materials required: 20 gold ingots, 10 real silver, 2 Ruby; The Blackstone abyss key (task) needs to be turned on and off. The key is to go through the Blackstone bar and ask the bar owner Prag to buy 6 bottles of black iron beer for NPC or complete the task of enchantment NPC. Smelting black iron ingot: near the entrance of MC in Blackstone abyss, there is a furnace guarded by fire element. To make black iron equipment: you must use the black stone abyss isendios 300 Hellfire Peninsula learning expert level mining 300 magic iron ore smelting to about 315 Hellfire Peninsula 325 refined gold smelting to about 340 Hellfire Peninsula (no but can rise point) 350 henggold smelting to about 360 Hellfire Peninsula (no but can rise point) 350 magic ingot smelting to about 370 Yuhuo Peninsula (no, but it can go up) the first place of 375 krypton gold mine is Thunder Mountain, where there is more copper (pay attention not to throw too much blood when jumping off the mountain ^ - ^!) Copper is more important. Copper is also needed when processing bronze. In a sense, it is more important than tin. Damodo (nomorrigan comes out, a few holes are filled with copper) is digging tin in a pit under the taurazu camp. It's a small place. It's a humanoid monster. I forgot its level. It's probably more than 20. It's a good place to make money. At the same time, it can also dig mines. This brush copper tin and a small amount of silver, after going out from here, we walked into the thousand needle stone forest. In addition, you can also go to the wetland (in the cave next to the waterfall in the north of the map) to mine tin. You can practice up to 125. There are mainly three places for thousand needles. The first one is Feiyu cave, in which there are about 30 birdmen, and three ore spots are painted with 2 iron and 1 silver. The second is to walk down from the cave, which is the split hoof castle in the Centaur cave opposite luanfenggang. It's bigger than the flying feather. But if you stand in the middle, you can also search the vein of the whole cave. There are iron and silver brushes here, but there are almost no rules. Sometimes you brush a real silver mine in the innermost part. There are also some tin mines and copper mines on the way from Feiyu. If there are not enough mines in the early stage, we can continue to dig here. Third, go out of the Centaur and walk towards the elevator. Along the way, you may find tin. Besides, there is a cave under the elevator. The iron ore is relatively concentrated. Walk to the direction of shagang after the elevator. There is a mining spot near shagang, and there is also a chance to dig iron. Then walk to the wind nest, which is the bipedal flying dragon. This place is relatively scattered, so we should be careful not to miss a place, especially here there is a small slope from the bottom to the top of the mountain, and there are two mineral spots on the top of the mountain. Here, then run to Feiyu cave. There are still mines to dig on the road. In this way, we can change places after 175. There are also many iron ores in the wasteland where audaman FB goes out. When the real silver ore arrives at 175, it can be transported to the gallows in Aoshan. There are extremely rich secret silver ore, iron ore, silver ore and real silver ore in it, which are unearthly. After 230, it spreads to Heishishan, goes out of FB, and goes up to the scorching plain. There are many kinds of minerals, such as true silver (230) / black iron (230) / SE silver (250), which can be upgraded to 275. By 275, we can mine Fu se Silver
