2. [best answer] the difference between silica and quartzite lies in the amount of silicon content. Usually we call it silica. As for the price
different kinds of silica have different prices. Divided, half, all

3. Quartz ore is a kind of high-purity silica ore with high purity and high value. It depends on the market to make money.

4. These people don't work at home all year long. They say that there are mountains and mines here. They want to recruit owners from other places. They just want to make money from them. Developers should not be deceived

5. Quartz ore is mainly used to make quartz slate. The sales volume is large, but it needs to be made into powder. The powder size varies from dozen to dozen. A good one is about 300 yuan per ton. The quality depends on the manufacturer of quartz slate. You need to ask

6. Quartz itself does not have radiation, do not know whether it contains radioactive substances, need to be detected

7. Generally speaking, the components of crystal and quartz are almost the same, mainly silicon dioxide. The difference is that crystal is relatively pure silicon dioxide with almost no impurities (trace elements), and the purity is more than 99.99%, while the purity of quartz is not so high. Generally speaking, colorless and transparent quartz crystal is called crystal, The opalescent, translucent or opaque quartz crystals with poor transparency are called quartz.
in addition, there are several mineral crystals with similar color and transparency to crystals in nature, among which calcite is the most common one. Calcite with higher purity is colorless and transparent, but its hardness is far less than that of crystal, so it is easy to scratch with a knife (it doesn't need too much force), The main difference between the two is that the hardness of crystal is relatively high, and there is usually no scratch. The most typical point is that the complete crystal is columnar, with six faces, and there are six faces around the tip of the top

8. Explosive is mainly used for blasting, but some of them can be dispersed by using excavators equipped with muzzle.

9. Stupid Emerald

10. Quartz is one of the most widely distributed minerals on the surface of the earth, and it is also widely used. As far back as the stone age, people used it to make stone axes, stone arrows and other simple proction tools to hunt for food and fight against the enemy.
