Common ore pool
there are some points for attention in account setting. It is suggested to set a common account in e-mail
then there is the most important miner account setting. Miner obviously refers to CPU or GPU. You need to set an account for each CPU or GPU. Suppose you have two hd7990, you need to set four different accounts for four GPUs
after the account registration, it's time to take the second step. Download the bitcoin miner. Here we recommend the small and easy-to-use guiminer, which can support CPU, oepncl, CUDA and other computing modes. Your CPU and graphics card can achieve maximum performance
guiminer, a bitcoin miner, still needs to make certain settings. After the interface is changed to Chinese, it will be very simple
if the setting is correct, click the "start mining" button, the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, and you can also monitor the state through gpu-z or graphics card driver
the computing power displayed by guiminer is only a theoretical value. To know the actual output of bitcoin, you need to log in to the mine pool website, btcguild, to monitor your account information
now let's assume that you have g up several bitcoins, which naturally exist in btcguild, a foreigner's website. They can't be traded or converted into paper money for the time being
the functions provided by bitcoin China trading platform are clear at a glance, and you can understand them as soon as you read them, so you don't need to introce them any more. After you register, you can study them slowly
click the "bitcoin recharge" function of bitcoin China trading platform, and the system will provide you with a one-time bitcoin digital wallet address. This address can only be recharged once (for security reasons of the platform). After successful recharge, it will be invalid, and then the system will provide you with another address. Remember to update the wallet address in time every time, Otherwise, it will lead to recharge failure or loss
OK, now we import bitcoin from foreign websites into bitcoin China website, and it's up to you to deal with it. Keep it for appreciation, listing and selling, and exchange it for RMB. Specific how to operate, this Chinese website is easy to operate, we slowly study it
finally, let's talk about the equipment used in the bitcoin mining test. At first, I thought it was just an ordinary hd7870, but its computing power was much better than that of the ordinary hd7870. The key is that guiminer recognized it as the Tahiti core, which is the only core of hd7900 series. Looking at gpu-z, the card originally had as many as 1536 stream processors, Generally, the hd7870 of Pitcairn core has only 1280 stream processors. No wonder Dylan's graphics card has super computing power
for friends who hang up for a long time, performance is not the most important, and stability is the most important.
Step 1: prepare mining machines and pools
if you want to dig bitcoin, you must prepare professional equipment. At present, there are many professional mining machines on the market, and the pool is also essential. When you choose a pool, you should also compare the output and income gap of each pool, and then choose the most suitable one
Step 2: register and set the mine account
after the mine is ready, register the mine account and set a common email. When setting the mine account, each CPU or GPU needs to set a mine account
Step 3: download the bitcoin miner
after you register and set up your account, you need to download the bitcoin miner. When downloading the miner, be sure to choose the miner that can make your CPU and graphics card play the most function. After downloading, set the server, user name, password, device and so on
Step 4: Mining
after setting up the miner, click the "start mining" button, the miner will enter the state of full speed operation, and the miner will start mining automatically.
Jigging is the most widely used coal preparation method in China's coal preparation plants, followed by dense medium separation and flotation, and other methods are rarely used. This paper introces the heavy medium shallow trough separation. The working principle is that the suspension is fed into the separation tank through two parts, and the upward flow is fed from the lower part. The function is to keep the suspension uniform and stable, and to disperse the materials at the same time
the horizontal flow is fed from the side, which can keep the density of the upper suspension stable and form the horizontal medium flow from the feeding end to the discharging end, which can transport the floating coal. After the selected coal enters the separation tank, it is completely immersed in the suspension under the action of the regulating baffle, and stratification begins. Low density materials such as clean coal float in the upper layer, and high density materials such as gangue sink in the bottom layer
in the process of sinking, the low-density materials mixed with gangue are fully dispersed and continue to float e to the effect of upwelling. Under the action of horizontal flow, the low density material floating on the suspension is discharged from the discharge port to become clean coal procts. Under the action of the scraper, the high-density material sinking to the bottom is discharged by the head chute to become gangue procts
extended data
for coal, the main washing methods are gravity coal preparation, floating coal preparation and special coal preparation. The commonly used method is gravity coal separation, which is mainly based on the density difference between coal and gangue. The density of coal is generally between 1.2-1.8, and the density of gangue is generally above 1.8. The coal and gangue with different densities are separated by gravity in the coal separator
Gravity coal preparation can be divided into jigging, heavy medium, chute, chute and shaker. The three most basic technological processes of coal preparation plant are preparation before separation (crushing, screening and classification), separation and treatment of procts after separation. At the same time, dense medium coal preparation includes five major processes: coal flow, medium flow, circulating water system, slime water and clean wateris first screened for grinding with large particles, and then gravity separation is carried out
shaker, chute and jig are commonly used in gravity separation equipment
