Copper ore refers to the mineral aggregate with a certain content of copper ore and can be recycled at the present stage. In general, copper ore is occurred in ore inside as sulfide, and associated with a certain amount of lead and zinc ore. Crushing-grinding-flotation is the most common copper ore dressing process. Taking Xinhai copper-lead ...

2021-4-2 Froth Floatation Method. This method is especially applied to sulphide ores, such as galena (PbS), zinc blende (ZnS), or copper pyrites (CuFeS 2). It is based on the different wetting properties of the surface of the ore and gangue particles. The sulphide ore particles are wetted preferentially by oil and gangue particles by water.

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

2021-5-3 3. Poling : Copper is purified by this method. The molten impure copper (called blister copper) is stirred thoroughly with poles of green wood. The gases escaping from the poles reduce the oxide of metal to the metal. The surface of the molten copper is kept covered with powdered charcoal so that copper may not be reoxidized in contact with air. 4.

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".
