Separate lead and cooper by gravity separation process

lead and cooper by gravity separation

Inhibition of Lead and zinc, lead zinc copper or lead zinc copper flotation mixed concentrate gravity separation method, belongs to the field of non-ferrous metal ore dressing technology. So-called mixed concentrate reselection plus PBS inhibitor. Containing the following steps: the mixed concentrate first joined the PBS inhibitor, and then into the shaking tabling; after tabling, concentrate with lead concentrate, the concentrate and tailings containing with with lead and zinc, lead zinc copper or lead copper concentrate and tailings; again or repeatedly will concentrate, tailings obtained by the above tabling, finally lead concentrate and zinc concentrate, zinc and copper concentrate and copper concentrate. Because of the existence of lead sulphide inhibitor, the floatability of the lead sulphide is completely inhibited, the high proportion of characteristic prominent PBS, thus shaking heavy selected, can easily be separated from multi metal in the mixed concentrate of lead sulfide. Concentrate metal elements mutually containing low, the affiliated metal concentrate and the main metal concentrate can meet the requirements of metallurgical standard, and has significant economic benefit.

lead and cooper by gravity separation1. Inhibition of lead and zinc, lead zinc copper or lead copper flotation mixed concentrate gravity separation method, which is characterized in that: the income of flotation lead zinc, lead zinc copper or lead copper mixed concentrate gravity separation, add the lead sulfide inhibitors usually used in flotation process.

2. Inhibition of gravity separation method, which is characterized in that:
(1) through flotation process, obtained lead zinc, lead zinc copper or lead copper mixed concentrate add lead sulfide inhibitors usually used in flotation, then sent to shaking table for gravity separation.
(2) through shaking table gravity separation, concentrate obtains lead concentrate, second concentrate and tailings contain lead zinc, lead zinc copper or lead copper.
(3) once more or repeatedly obtained second concentrate, tailings, and separation water including inhibitor sent to shaking table for gravity separation, finally get lead concentrate and zinc concentrate, zinc and copper concentrate and copper concentrate.

Non-ferrous metal metallurgy, whether the fire method or wet, must use the concentrate. Lead zinc, lead zinc copper or lead copper mixed ore beneficiation difficult. Because the flotation separation inhibitory control point is very difficult, concentrate metal elements often each other with high output. Because of galena has natural flotability, thus gravity concentrate metals contains each other too high.
