How to Sample Gold Ore - Mineral Processing & Metallurgy

It is on gold ores carrying relatively coarse gold that the real problem arises, because the wt. %m is low and the dm is high. In ore assaying 0.1 oz. per ton, the wt. %m =4.2 X 10 -4% dm = 10.3. In ore assaying 0.1 oz. per ton, the wt. %m =4.2 X 10 -4% dm = 10.3.

In some cases the gold in the ore is extremely fine sized, and using mercury to capture it makes sense. This is also true for operators processing large quantities of hard rock material. Ive done up a web page on using Mercury to capture fine gold and you can view it here.

Sampling of run-of-mine mill feed— A practical approach

The first sample was a low- grade gold ore (about 5 g/t gold) mill feed sample from a South African gold mine. The particle size was 95% -12 mm. The second sample consisted of boulders of high-grade gold ore (about 60 g/t) that were crushed to yield a 95% -12 mm product.

Gold mining - Wikipedia

Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the worlds deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers.
