Zinc sulfide also reacts with sulfuric acid under these conditions: As shown in the equation, the process also produces sulfur as the element, and this can be used to make the sulfuric acid required. Bioleaching. Very high zinc extraction rates (up to 99%) from lowgrade ores (as low as only 5% zinc) can also be achieved using bacterial action.

How Is Gold Extracted From Gold Ore? Sciencing

Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.
