optimisation of gold recovery by selective gold flotation

Optimisation of gold recovery by selective gold flotation for copper-gold-pyrite ores. ... Abstract. Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the

Jul 12, 2014 · Selective floatation of base metal sulphide minerals can be achieved by using selective reagents. Sequential floatation of chalcopyrite–sphalerite from Taknar (Iran) massive sulphide ore with 3.5 % Zn and 1.26 % Cu was studied. D-optimal design of response surface methodology was used. Four mixed collector types (Aer238 + SIPX, Aero3477 + SIPX, TC1000 + SIPX and X231 + SIPX), two

Aug 01, 2002 · Sedimentary dolomitic phosphate ores are difficult to treat by flotation, and high-grade phosphate concentrates with high recoveries are difficult to obtain. The literature indicates that the reagents required for beneficiation of such ores are generally dictated by the nature of the gangue. In this paper, the optimum flotation parameters necessary for enhancing the grade and recovery of a

Nov 22, 2018 · Selective flocculation utilizes the differences in the physical-chemical properties of the various mineral components in the mixed suspension. It is based on the preferential adsorption of an organic flocculant on the particular solids to be flocculated, leaving the remainder of the particles in suspension. In order to understand the mechanics

It is usual when moving from bench-scale to bulk flotation that there is a drop-off in performance both in terms of the grade of the concentrates and the recovery of graphite. PPL's expanded plant, simply put, now consists of a new circuit that is essentially a pebble flotation circuit and the old circuit, which is a bulk flotation circuit
