Cupellation Furnaces for Precious Metal Assaying

Lodge records that the loss in cupelling 200 milligrammes of gold with 10 grammes of lead ranged from 0.15 per cent, at 775° to 2.99 per cent, at 1,075°. The addition of 0.05 grams of copper increased the loss of gold from 0.15 per cent, to 0.25 per cent. In these cases the gold beads were apparently weighed without being parted.

Pressure Oxidation of a Refractory Sulfide Concentrate and Thiourea

Pressure oxidation of the refractory sulfide/carbonaceous ores has gained world-wide acceptance. Compared with roasting, pressure oxidation yields higher gold extractions from ores or concentrates and enables better handling of environmentally sensitive impurities. Normally, gold is extracted from neutralized autoclave leach residue by cyanidation.

Leaching Gold from Finely Crushed Ore (Sand Leach)

When dealing with exceptionally reducing ores compressed air may then be introduced beneath the filter, if necessary, as is done at the Homestake. The system of draining dry between washes as compared with continuous leaching has been known to result in an increased extraction of 25% under actual working conditions on combined gold and silver ore.

The chart/table below are crude budgetary estimations for the cost of major plant equipment. Actual cost will vary depending of the process details and detailed equipment list and origin. Please use this to decide if your project and dream for becoming a miner or mining company is something you can afford. This is only an approximation.

Pressure Filter

In these types of filter the MWF is conveyed under pressure from the upper chamber, the pressure filter, down to the lower chamber, the tooling machines or central system (Fig. 8.6).In contrast to the band filter systems described before, the cleaning process of pressure filters is carried out in a closed pressure chamber.

Carbonaceous Gold Ore Mineralogy

With non carbonaceous ore containing gold in the metallic state, a similar experiment showed only eight per cent dissolution of gold. Most of the Carlin carbonaceous ores contain from 0.4 to about 1.0 per cent organic carbon, with occasional samples as high as 4.0 per cent. Particle sizes vary from less than one µm to over 100 µm.
