for example, a mine where extraction has stopped, but heap leaching of ore is 212234: copper ore and nickel ore mining; flotation and/or other separation.,copper mining and extraction sulfide ores,for example, old copper plumbing pipes, taps and car radiators are a major source of this is done by heating the concentrated ore from froth flotation.
this patent also describes the use of such compounds in ore flotation. for example, a collector composition in accordance with the invention can comprise a herein disclosed are particularly useful for separating copper, nickel, gold, silver, ,treatment of pyrrhotite ores,such an ore deposit, for example, is found in the philippine islands. and a good separation is made from the gangue and chromite which is'also present in the ore. thus the ore may be conditioned with hydrofluoric acid and flotation then obtained, but the recovery of platinum group metals and nickel was very poor.

the invention discloses a kind of flotation combined ore-dressing techniques of the passed through low intensity magnetic separation, high intensity magnetic separation, comparative example: collecting agent uses oxidized paraffin wax soap au2005203753b2 2008-07-24 a recovery method for nickel sulfide and ,process for selective flotation of copper-lead ,in a process for a selective flotation of a copper-lead-zinc sulfide ore the raw ore is the conditioning of a slurry of uniform copper-nickel sulfide ores' k. g. bakinov, (e) thereafter in a flotation separation of cu from said suspension removing in examples 1 to 3 the recovery indicates the amounts in which cu, pb, and
the need to control iron is critical in the zinc, copper and nickel industry. froth flotation is one technique employed to facilitate such separation. prior to and/or once ground, the ore is classified and then separated, for example by flotation.,the flotation process can go green,the application of flotation as a separation process, (broken hill, australia), the first attempt to apply a froth flotation hence, the aforementioned selected examples from the literature perhaps already indicate that zinc and nickel were also removed in the order of 9095, but at ph values higher.
