1. Introduction. At present, more than 35% of China's gold resources (with a total amount of more than 1,000 tons) are difficult to be exploited and smelted, and about 700 tons of gold ores with high arsenic, antimony or sulfur are difficult to be directly cyanide leached (Lei et al., 2016).However, as the gradual depletion of easy-to-treat gold ore …

Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., …

1 Wash, filter, and grind the granite ore into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc. The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution.

Bioprocessing can be applied in gold recovery/extraction. These processes can be attractive for use on low-grade gold ores that are too expensive to process using conventional processes, and for ores that contain impurities which, in turn, contaminate conventional processing equipment (e.g. arsenic in gold ore).

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
