First there is a deduction from the contained metal assay to compensate the smelter for processing metal losses. If the concentrate grades around 50% lead and 20% zinc, then around 3% of the lead and 8% of the zinc will be deducted. This is effectively part of the treatment fee and is usually higher for lower grades.

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is necessary to be ...

Lead Zinc Flotation Recovery Vs Grade Chart. The recovery and grade of unwanted lead and zinc was very low when compared to the other flowsheets. Lead in the feed was, on average, 36% recovered into a concentrate, grading 55%. Similar to the copper circuit, the grade and recovery of copper and zinc to the lead concentrate was very low.
Through the flow chart of ore grinding, initial flotation of lead minerals, and separation of zinc and S minerals, Pb concentrate with Pb grade of 64.55% and Pb recovery rate of 84.47%, and Zn ...
Zinc concentrates assayed 258 grams per tonne silver, 3.2 grams per tonne gold and 48 per cent zinc at a zinc recovery of 55 per cent. Lead and zinc recoveries in rougher concentrates, prior to cleaning, were 48 per cent and 93 per cent, respectively. More testing is required to better define flotation conditions and improve lead and zinc ...
