Copper LPF Leach Precipitation and Flotation Process

Approximately 40% of the total copper occurs in non-sulphide form. Metallurgical tests conducted on the ore showed that sulphidization was ineffective to recover a significant part of the oxidized copper. However, the leach- precipitation-flotation process, commonly referred to as LPF, was shown to be economically feasible.

Copper Leaching from Refractory Flotation Tailings

copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings. As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used [12].

Copper Ore Processing Methods

Sulfide-filming of the carbonates followed by flotation of the filmed minerals, or direct leaching followed by precipitation of the copper from the solution may be employed for such ores. Ores containing sulfide copper minerals together with enough sulfides of zinc, lead, iron, or other metals to warrant use of differential flotation to ...

Copper oxide is more difficult to recover than copper sulfide. Presently, the three main treatment methods of copper oxide are flotation [2,3], leaching [4], and beneficiation-metallurgy combination processes [5]. The flotation method can be divided into the two following types: direct flotation and sulfidation–xanthate flotation.
