The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

The copper is sold for $113,000 after additional processing costs of $15,500, and the manganese yield sells for $71,000 but requires additional processing costs of $12,500. The joint costs of processing the raw ore, including the cost of mining, are $215,000 per batch.

The price of the ore depends on two things: (1) the value of the copper it contains, minus (2) the cost of recovering that copper (mostly excavating it from the ground, separating it from the gangue minerals, recovering it as metal, and getting it...

Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods. Thirty-seven

Mar 04, 2019· Sorting of ore to increase grade and reduce subsequent processing and transport costs, and; Sorting of ore to bring forward cash flow. Guthrie said: "The first case adds value to the project by conversion of waste to ore. On this basis, recovery is not critical and the value of the recovered material needs to cover processing costs plus margin.

The copper is sold for $145,000 after additional processing costs of $23,500 and the manganese yield sells for $125,000 but requires additional processing costs of $30,500.

By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.

hydrometallurgical process for processing copper sulphide concentrates to metal. ... reserves of copper ores that are amenable to heap leaching are limited, with current technology. In particular, primary copper sulphides, (chalcopyrite), are ... Figure 3 presents the historical copper prices and TC/RCs from 1986 to present.

Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 %

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.
