2009-8-26 froth flotation performance obtained with a bornite-rich copper sulphide ore from Okiep Copper Mine with a feed grade of 1.8% copper. Batch flotation tests were used to assess the performance in terms of mass-water recovery, sulphur grade-recovery and copper grade-recovery relationships and the Klimpel rate constant for copper recovery.

2020-3-25 copper content of the slags range between 0.8 to 5 wt. % and this is considered too high for disposal to the environment. Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that

2012-8-13 The 'oxide' flotation plant no longer exists, neither does the high grade leach-electrowinning plant, this site now being occupied by the smelter. Oxidised copper flotation was always inefficient, as in the suite of copper-containing minerals mined at Nchanga are minerals which respond poorly to the froth flotation process, notably cuprite ...

2008-2-4 Copper-bearing Gemstones. When Paraiba tourmaline first reached the market in the early 1990s, it led to a tremendous interest in copper-bearing gemstones. We receive many emails from customers asking whether particular gems in our inventory are copper-bearing. There seems to be a perception in the market that a gem containing traces of copper is inherently valuable.
