Features and Flotation of Complex Cu-Pb-Zn Sulphides

Problems arising during flotation of complex Cu-Pb-Zn sulphide ores are in general of geological origin. The features of these ores are reviewed, stressing that mineralogical studies extending to process mineralogy are prerequisite for a consistent flotation process. Some examples affecting flotation are

Distribution of Sb minerals in the Cu and Zn flotation of

2015-10-15 1. Introduction. Generally, antimony (Sb) is known to occur as a trace element in massive sulphide ores. It is regarded as penalty element because it lowers the quality of Cu concentrates produced from ore and sent to the smelters (Minz, 2013 and references therein).Typically, penalty charges are imposed for Sb contents of 0.1–0.3 wt% in copper (Cu) concentrates (Larouche, 2001).

Current Situation on Flotation of Cu-Pb-Zn Sulfide Ore

Floatation Process Preferential Flotation. When there are obvious differences in the flotability of minerals, the preferential flotation process is generally adopted. Various minerals are separated by flotation in the order of flotability from high to low. In a beneficiation tests of a Cu-Pb-Zn polymetallic sulfide ore, the sequential preferential flotation process by the order of copper- lead-zinc was adopted, and the

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 depressant

The Batu Hijau Concentrator uses sea water for processing a gold-rich phorphyry copper ore (chalcopyrite-bornite) (Castro, 2012), while CBI processes a complex Cu–Zn sulphide ore using dissolved metal ions and sulphide ions, mainly in the form of SO 4 2 − and S 2 O 3 2 − (Bıçak et al., 2012).

Indium pre-enrichment from a Canadian sulphide ore via

2020-9-1 In this work, the flotation was adopted to pre-enrich the In from a Canadian sulphide ore. The findings of this study can provide a basis for the pre-treatments of In-bearing sulphide ores. 2. Materials and methods. 2.1. Minerals and reagents. The indium (In)-bearing raw ore samples were obtained from a Canadian sulphide deposit.

A Flotation Technique for a Sulfide-Oxidized Cu-Co Mixed

Conventional floatation treatment has poor effects on recovering Cu-Co sulfide-oxidized mixed ores due to the high oxidation rate and large amount of carbonaceous mud of the ores. The research results showed that the pre-removal of carbonaceous mud asynchronous flotation process got a better flotation

Distribution of Sb minerals in the Cu and Zn flotation of

Abstract The Rockliden massive sulphide Zn–Cu deposit contains minor amounts of Sb minerals. The Sb mineralogy is complex in terms of composition, micro textures and mineral associations. The main Sb minerals comprise tetrahedrite, bournonite, gudmundite and Sb–Pb sulphides such as meneghinite. The presence of these minerals is especially critical to the quality of the Cu–Pb concentrate
