This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold associated with quartz.

fine gold particles after grinding the ore in a ball mill and concentrating by panning. Miners separate the gold from the The extraction of gold from ore differs very little from one arti- his own capital to introduce innovative technologies to design and implement safer, more responsible mining practices.

8-6-2020Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size.

The Handling Materials and Main Types of Ball Mill: Ball mill is a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

In 2017, a secondary crushing circuit was installed to remove the SAG mill throughput bottleneck and increase production of highly competent underground ore from 1.35 to a minimum of 1.7 Mt/a. This paper discusses the findings from the trial phase, the circuit design, project delivery, site optimisation, and the plant performance.

Mined ore from the stockpile is fed into a silo by a front-end loader. The broken ore is moved from the silo by an apron feeder over a vibrating grizzly, with the oversize passing through a single jaw crusher (1100x900mm). Undersize and crushed ore at minus 15cm size is conveyed to one of the two SAG mill/ball mill combinations.

Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.

The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded with enough gold it is removed from the circuit and sent to elution where the adsorption process is reversed and the gold is stripped off the carbon back into solution, electrowon and smelted into bars.

1-1-2016It can, therefore, be concluded that autogenous grinding was not suitable with this particular gold ore, but semi-autogenous operation with about 8% ball charge was the preferred option. Based on these test results, a 6.7 m diameter 2.1 m length SAG mill and a 3.3 m 6.1 m ball mill were installed for commercial operation in closed circuit with a hydrocyclone.

stage crushing circuit and a single ball mill (previous design was single stage crushing feeding SAG and ball mills). This revised configuration is designed to achieve a throughput in the order of 3.5 – 4.0mtpa in fresh ore (previous design forecast 3.0mtpa). This is expected to deliver an average gold production range of 105,000 –
