Answer: How to refine gold is that gold is naturally developed in nature rather than the product of artificial synthesis. In fact, it is different from the composition and the quality of refining. Most of the ore must be used by digging, crushing and cleaning. The larger gold is directly used, and it is very small. Cura gold is the gold that we can refine after smelting. Generally, the purity of gold is very high, and the density is relatively fine. The sand gold is a gold mixed with stone sandpaper in the river or in some relatively low places, and then artificially cleaned. 1. After mining, the washing and other metals were called a qualified gold. 2. Cooked gold is smelting, and common gold bars are used. 3. Sand gold is produced from the bottom of the river.
