The world experiences show that copper can be cost-effectively valorized from flotation tailings. One example is the old flotation tailing dump of the Miami mine in Arizona [1]. The old Bor flotation tailing dump is located on the border of urban and industrial part of town, and beneath it a collector of municipal waste water is situated.

THIS invention relates to a process for recovering value metals from ore ( 50 ) configured such as to substantively reduce or eliminate the need for a tailings storage facility. This object is achieved through an integrated processing system designed to enhance the ratio of sand residue from coarse flotation ( 62 ) to the amount of tailings arising from fine flotation ( 72 ), and then

Nov 11, 2020Flotation is about recovery of valuable materials. The pulp density is on the hands of the operator to make the decision on having a maximum recovery or to lose valuable materials to the tailings (waste). Operators need to set a target for the slurry density feeding the flotation to keep the process operating at its optimal conditions.

The slag was concentrated in a Knelson type centrifuge, two concentrates (C1 and C2 and a tailing T1) being obtained. In order to improve the recovery, three series of rougher flotation tests were conducted on the tailing T1. The variables analyzed were: particle size, type of collectors (xanthates, di-monothiophosphate) and flotation time.
