As main gangue minerals, calcite, dolomite, and some silicates are present in both ore types. Before 1960, the lead-vanadate-containing ore from different ore bodies was processed using gravity concentration. The processing plant for flotation of lead, zinc, and vanadate minerals was introduced by the end of 1961 and closed in 1978.
lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 °C (621 °F), coupled with its easy

A possible difference in the flowsheet might be the addition of a gravity preconcentration stage for lead. In some cases, the heavy liquid separation is performed prior to lead zinc oxide flotation. The reagent scheme selection is very dependent on (a) type of gangue minerals present in the ore and (b) type of lead and zinc oxide minerals.

The test had been carried out on a lead oxide ore (18.57% Pb) from Kazakhstan, which had a high oxidation ratio (above 95%) and complexly intergrowed with plenty of alkaline gangue minerals such as calcite and dolomite. A joint flowsheet that combined the gravity separation with flotation was developed to recover the lead, during which flowsheet, a new effective slurry regulator was used.
Lead is hardly obtained from lead ore anymore, however, but instead from recycled lead scrap. Today, more than 50 per cent of global requirements can be met from this.

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.. Galena is one of the most abundant and widely distributed sulfide minerals.It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite
So, qualitative and quantitative understanding of minerals of specific ore is an integral part of selection of appropriate process flowsheet and optimization of plant performance .
