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
If the concentrate grades around 50 lead and 20 inc then around 3 of the lead and 8 of the inc will be deducted. This is effectively part of the treatment fee and is usually higher for lower grades. With regard to accompanying precious metals silver above an agreed minimum content will be paid but generally gold is not paid for

Read MoreSelective sulphide concentrates with low arsenic content were tried to be produced by froth flotation. Individual concentrates of Pb Zn and Cu assayed 67.54 Pb and 61.49 Zn and 23.31 Cu where corresponding recoveries were 73.0 and 77.1 and 38.7 respectively. Arsenic contents were less than 2000 ppm in the lead and inc con-centrates

However the role of calcium arsenate formation in reducing the concentrations of dissolved arsenic has not been well established. Therefore slurries with varying CaAs ratios were equilibrated and
