Beneficiation Process For Copper Mine In Canadian

Canadian copper mine introduction

Canada is the third largest copper producer in the world, after Chile and the USA. Most of Canada's copper prodcution comes from mines in Ontario, British Colombia and Quebec.Existing and future Canadian copper production is affected both by copper prices and by the prices of other coproduct and by-product metals.The production of copper in Canada is associated with the production of other metals (and sulphuric acid). There is no Canadian copper mine whose revenue from its domestic operations is derived entirely from copper.

Copper ore is generally oxygen or sulfur, and sulfuric acid reaction of blue-green copper sulfate. Copper has a wide variety of natural copper color. Bornite copper was dark red, blue-violet oxidation becomes patchy; lead-gray chalcocite; copper blue is indigo; tetrahedrite is a steel gray; blue copper is bright blue. The world's proven copper reserves of about 6 million tons, reserves of most countries are Chile, accounting for about one-third of the world's reserves.

Crushing and grinding stage

The extracted ore should be crushed by jaw crusher initially and then by fine crusher. When it gets the reasonable fineness, it is transported into ball mill by elevating conveyer and feeder, and is milled by ball mill.

Zenith is a professional manufacturers which produces crushing and grinding equipment. The technology of crushing and grinding equipment has reached the international advanced level.Jaw crusher which is used in primary and secondary crushing can meet most crushing requirements. Ball mill would be the essential equipment in fine grinding method immediately after crushing. Zenith ball mill is created with long life, great overall performance and minimal maintenance. Zenith ball mill is efficient equipment for grinding several supplies into fine powder.

Classifying stage

The subtle milled ore gets the next procedure: classification. There is a theory that if the weights of solid particles are different, the sedimentations will be different, and the mixed ore can be classified by screw classifier.

Mixing and floatation stage

The classified ore gets into mixing tank for fully mixing. At this stage, chemical agent for foam can be added. After fully mixing, the slurry will enter into flotation machine.When the floatation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee. Nowadays, Zenith is able to produce flotation machine not only the single cell type but also the open flow type to meet modern requirements.
