Sulfide Ore Grinding Copper

Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace. The liquid

How to Process Copper Ore: Beneficiation Methods and

28/5/2020· Secondary copper sulfide ore is easy to oxidize and more difficult to float than original copper ore. As for the grinding and floating process, it is more advantageous to adopt the stage grinding and floating process for refractory copper ore, such as the re-grinding and re-separation of coarse concentrate, re-grinding and re-separation of bulk concentrate, and separate treatment of medium ore.

Oxidative weathering of a copper sulphide ore and its

1/12/2016· In this study, a copper sulphide ore has been artificially oxidised for varying lengths of time and a series of grinding and flotation tests under several grinding environments were completed at each time interval to study the combined effect of ore oxidation and grinding pulp chemistry. The results highlight the importance of matching the right grinding environment to the oxidation degree of

In situ recovery of copper sulfide ores: Alternative

1/9/2020· There is a growing interest in exploring the application of bioleaching for treating copper sulfide ores of decreasing grade and located at larger depth by in situ recovery (ISR) for its potential savings in ore extraction, crushing, grinding and the avoidance of tailings. As copper sulfide ores are usually present in well consolidated rocks a crucial aspect for ISR to be successful is to

Copper Sulphide Ore Flotation Process-peter&x

Coarse-grained copper sulfide ore can use a stage grinding a stage floatation process, and the fine-grained copper sulfide ore can adopt two stage grinding- two stage flotation process. What's more, middling regrinding technology can reduce grinding energy consumption, which is widely used in ore dressing production. Xinhai is a professional mineral processing equipment manufacturer, who can

Mechanochemical sulfidization of a mixed oxide-sulphide

1/3/2020· Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency and recovery of copper in detail.

Copper Sulfide Ore Flotation Technologies-peter&x

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".

Sulfide Ore an overview ScienceDirect Topics

If sulfide ores containing iron and copper are to be smelted, an understanding of both the iron and the copper systems is needed. This is done by crushing and grinding the ores to liberate the nickel- and cobalt-bearing minerals from the other minerals. The ground ore is processed through two stages of flotation. The first stage of froth flotation separates the nickel-, cobalt-, and copper

Mechanochemical sulfidization of a mixed oxide

Copper Ore Grinding Machine crushermaintenance

Copper Ore Grinding Machine. The content of copper ore flotation and ease of iron sulfide ore closely. According to the number of sulfide copper ore iron sulfide content divided into two categories, one is dense massive copper ore, one is disseminated copper ore. The former is characterized by a high content of pyrite ore, sometimes up to 80% to 85% gangue content rarely, copper sulfide and

12.3 Primary Copper Smelting

Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation

Copper Smelting Chemistry Tutorial AUS-e-TUTE

A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC.

copper ore silica pdsasa

Copper Mining and Extraction: Sulfide Ores. This is either sold for industrial use or used to extract oxide ores of copper by leaching. Stage 4: Smelting with fluxes The calcine is heated to over 1200 °C with fluxes such as silica and limestone.

Copper Ore Crushing, Grinding & Flotation

Crushing and Grinding You will note that the Oracle Ridge project has utilized a two-stage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all -5 material for the cone mill with a screen in closed circuit. Normally a three-stage crushing circuit would have been more conventional, but with the type of
