Flotation separation of copper sulphides from arsenic

The arsenic content of Rosebery copper flotation feed is mainly present as arsenopyrite (FeAsS), containing approximately 46.0% arsenic with the remainder of the arsenic in copper sulphosalts (tennantite (Cu 12 As 4 S 13)), in a solid solution series with tetrahedrite (Cu 12 Sb 4 S 13). Tennantite contains approximately 20.3% arsenic. Characterisation of the rougher and cleaner concentrates

Flotation Copper Arsenic Advanced

Flotation Copper Arsenic Advanced Ion flotation removal of a range of contaminant ions from The effect of a natural, biodegradable surfactant obtained using a novel and efficient stone reaction between cysteine (a thiol-based amino acid) and an octanoyl (C8) compound, was investigated for its application to the ion flotation removal of low levels of different contaminant ions from

Arsenic in Copper Concentrate

Copper concentrates recently tested for mineralogy both measured about 0.44 percent arsenic content. This is above typical levels where penalties occur. Tennantite and enargite as well as Freibergite are copper arsenic sulphide minerals that respond to flotation in a similar manner to other copper sulphides. As such, depression of these

THE USE OF PULP POTENTIAL CONTROL TO SEPARATE COPPER

Keywords: flotation, copper, arsenic, controlled-potential flotation . INTRODUCTION . Arsenic is a dangerous pollutant and, as such, is also a penalty element in many base metal concentrates destined for smelting to recover the valuable metals. It is, therefore, of economic and environmental interest to remove arsenic at the earliest possible point in the beneficiation process e.g. the

Copper extraction Wikipedia

Copper extraction refers to the methods used to and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings. When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit where the density of the

A TECHNO-ECONOMIC COMPARISON OF PYROMETALLURGICAL

The most promising route for separating arsenic from copper at the flotation stage centers on the use of pulp potential control. In recent years CSIRO has demonstrated at laboratory scale, for a number of high-arsenic copper ores, that crude flotation separation between arsenic-bearing minerals and copper-bearing minerals can be made. The differences in specific minerals responses to changes

J copper concentrates with high arsenic contents

Advanced isoconversional methods were used the arsenic content in copper concentrates must be reduced to low levels (usually less then 0.5% As). Such levels are difficult to obtain by differential flotation of the ore from some sulfide deposits13. According to the World Health Organization14 (WHO) values of arsenic in the air above 1.5x10–³ µg/m³ present a high risk to human health

The Role of Arsenic in the Mining Industry

Arsenic in the mining industry . Atmospheric arsenic emissions from copper smelting represent the largest contribution of arsenic from the mining and metals industry by far and have been the focus of pollution control technologies and increasingly stringent regulations. [8] Arsenic can also be leached out of some metal ores by cyanide or acid rock drainage but can be captured and removed from
