The ore is sent into a single-cylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multi-cylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.

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.

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.

Gold processing steps: 1. Two-stage crushing. Large gold ore first enters the jaw crusher for primary crushing, then goes through the cone crusher for secondary crushing, separating out gangue minerals. The crushed gold ore is screened by a vibrating screen. 2. Grinding. The screened gold ore is sent to the overflow ball mill for grinding, achieving a …

There is no method for separating gold from silver, or other precious metals, when smelting. The ore containing the metal when melted will form an amalgam – an alloy of gold and silver, or whatever precious metals are in your concentrates.
