Using stirred tank bioreactors copper recovery could be further increased to 91. Because the smelter flue dust contains secondary and primary sulfides of copper leaching rates may vary. Continuous tests in two stages of air lift bioreactors were used to establish effect of pulp density

• ### Optimiation Studies On Recovery Of Metals From

The aim of the study was to recover copper and lead metal from waste printed circuit boards PCBs. The electrowinning method is found to be an effective recycling process to recover copper and lead metal from printed circuit board wastes. In order to simplify the process with affordable equipment a simple ammonical leaching operation method was adopted. The selected PCBs were incinerated

2019-6-28The relationship between mill head grade and recoveries and between mill head and concentrate grades for copper lead and inc were analyed and presented in the Mining Sourcebook in 1990. The study was based on 13-32 different operations and the results are shown in the table below 4

• ### Cutoff Grade Estimation Queensminedesignwiki

2019-6-28Cut-Off grade is the minimum grade required in order for a mineral or metal to be economically mined or processed. Material found to be above this grade is considered to be ore while material below this grade is considered to be waste. Although in a variety of units can be used the cut-off grade is usually expressed as
