The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct …
Bornite (Cu5FeS4), covellite (CuS) and chalcocite (Cu2S) are important sources in the world, and many ore bodies also contain some malachite (CuCO3.Cu(OH)2), azurite (Cu3(CO3)2.Cu(OH)2), cuprite (Cu2O), tenorite (CuO) and native copper. The sulphides, which yield most of the copper produced throughout the world, generally occupy the …
A method is being developed to characterise the floatability of small samples (5–10 g) such as drill core samples using the Julius Kruttscnitt Mineral Separation Index (JKMSI) (Coleman et al., 2006, Bradshaw, 2011, Bradshaw and Vos, 2013, Morgan et al., 2012).Its success has been demonstrated in characterising the variable copper recovery …
The copper-moly separation circuit was modelled using the test kinetics. The circuit was configured to include columns in every stage in order to minimize the amount of entrainment and to maximize the washing effect of the molybdenum concentrate. The circuit was designed with long retention times so that it could be operated with a slow ...
At Silver Queen mine (Canada) a combined lime-starch-SO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH 10.5–11.2, after which the pH is reduced to 5.5 with SO 2 (200 g/t) and the copper sulphide floated.
These consist of zinc and iron sulfide depressants which are added to the grind and a collector and frother for the lead-copper sulfides. The zinc is floated with additional quantities of a collector and frother after conditioning with lime and copper sulfate. The pH of the lead circuit is approximately 8.0 and the zinc is 10.5 to 11.0.

Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a …
