    50.6 EXTRACTION OF GOLD Chemistry Assignment

    Since gold is very unreactive it occurs in free state in nature. The primary sources of gold are (i) Alluvial gravel. It is found in the beds of certain rivers. It is referred to as alluvial gold. (ii) Auriferous quartz. Gold also occurs in the veins of quartz. This is called relf gold. EXTRACTION. The various steps involved in the extraction

    How Gold Works. 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 steel balls.
