Copper LPF Leach Precipitation and Flotation Process

Copper LPF Leach Precipitation and Flotation Process

May 16, 2016 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. Basically, the L-P-F process consists of dissolving the oxidized copper minerals with sulphuric acid and precipitating the copper as

Assessing a two-stage heap leaching process for Platreef

Nov 01, 2012 Nov 01, 2012 Samples of low-grade flotation concentrate derived from Platreef ore were treated with a two-stage heap leach process to determine the potential to run this process parallel to the convential concentrate–smelt–refine process for extracting platinum group metals, thereby adding value to the convential process via economic treatment of low-grade materials

WO2015095054A3 - Process for flotation leaching copper

A method [100] of leaching a metal sulfide ore is disclosed. The method [100] may comprise the steps of: providing slurry [3] having metal sulfide ore particles therein; subjecting the slurry [3] to a flotation step [2] at a pH level above nine to obtain a first concentrate [15]; subjecting the first concentrate [15] to an acidic leach solution [27]; subjecting the first concentrate [15] to a

Leaching, flotation and thickening are fundamental steps in modern mining separation processes. Achieving an optimal separation however is a complex task due to the many interconnected variables. All three processes use chemicals which are one of the main cost drivers. And they consume also a lot of water, which in some mining regions can be a

An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate. The process mineralogy analysis showed that the sulfur content reached 46.21%, and 81.97% of the sulfur existed as elemental sulfur which was the major mineral in the residue and primarily existed as pellet aggregate and biconical
