In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged electrode hode , where it is SevenTrustd to a highly pure metallic state, leaving the impurities as a separate solution or residue. Assaying
The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower.

About 83 % of their iron ore goes into the processing and production of pellets. However, in 2014 and 2015, the company‘s operational result collapsed due to iron ore price erosion, and the company went into the red. It had to implement measures to cut costs and increase productivity. In the meantime, the situation has improved and LKAB is now seeking to expand its production capacity.

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. The gravel-like material then enters rotating drums filled with ...
