Through the flotation test of pure minerals and actual ores, it was verified that the new collector GCI of sulfide ores is superior to butyl xanthate in selectivity and collecting ability, and is more suitable for flotation of the complex and refractory copper sulfide with low grade and fine dissemination.

The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copperbearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, which is mostly overlooked in the literature.

Sodium Isobutyl Xanthate (MCCIBXS) Historically been considered a good choice for the flotation of sulphide ores such as copper, lead, nickel and zinc. Dithiophosphate and Mercaptobenzothiazol Blend (MC404) A mixture of dithiophosphate and mercaptobenzothiazol widely used in tarnished and secondary copper ore flotation, also used in tarnished lead and zinc ore flotation in alkaline circuits.

Keywords: Copperleadzinc sulfide ore, Preferential flotation, Combined depressants. Abstract. According to the mineralogy of the polymetallic ore,the process of preferential flotation of copper was adopted, and the separation of lead, zinc and sulfur were carried out and implemented．Four products, including copper concentrate assaying % Cu at a recovery of %, lead concentrate ...

Flotation of non sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery for example heap leaching In Zambia and Zaire however siliceous copper oxide ores are floated with fatty acid collectors and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then grade (0 17 percent Cu 0 73 g t Au) Methods used .

 · High sulfide gold ore refers to 20% 30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotationcyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for highsulfide gold ores.

Kansanshi copper mine is situated in the north western province of Zambia. As a result of the mineral variations, the processing plant treats three distinct ore types, viz. oxide, sulphide and mixed.

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silie. (2) Coppersulfur ore Called copperbearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Effect of seawater main components on frothability in the flotation of CuMo sulfide ore 19 Frothing agents are employed in flotation to facilitate air dispersion into fine bubbles and to stabilize the froth. Froth stability depends on the frother type and concentration, but also is a function of other variables, such as particle size,
