Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold-containing solution is leached. Then used the method of carbon adsorption, zinc powder displacement device and so on to separate gold from the liquid. [Advantages] Gold Heap Leaching Processing Line Simple process, less equipment; Small investment, yield quick returns, and low cost; The nature, grade, quantity of ore has strong adaptability. [Process Description] The raw ore is crushed into fine particles by using jaw crusher or cone crusher produced by Xinhai; The crushed fine ore will be heap on the waterproof ground, and set drain aside the ground in advance; According to different leaching elements, prepare right leaching solutions. For example, gold heap leaching commonly adopts cyanide. Then the large pil...
