The polymetallic separation flowsheet of copperlead bulk flotation copperlead separation - priority flotation zinc and pyrite from the bulk flotation tailings was used.The concentrate indexes of the grade of copper, lead, and zinc were 20.10, respectively, and the recoveries were 75.
Typical lead-copper-zinc sulphide minerals were found hard to be separated selectively by froth flotation in the plant practice operation due to part of sphalerite was progressively entrapped into lead-copper bulk flotation.A series of de-zincing on lead-copper flotation tests has been conducted in the laboratory to reduce unwanted zinc content.
In parallel, the secondary ions present in seawater cause a colloidal precipitation and a strong buffering effect, which difficult the operation at high alkaline condition.The objective of this review is to present a summary of the current knowledge on the subject of seawater flotation processes, highlighting the copper sulphide ores flotation.
Colloidal zinc hydroxide can occur at the range of alkaline ph values used at the rosh pinah plant during the selective flotation of galena and sphalerite if both zinc sulphate and sodium cyanide are used.However, it has been shown that sphalerite from the rosh pinah composite is primarily activated by copper ions present in the flotation pulp.
