Lead ore also requires processing to remove rock and mineral impurities to achieve a suitable concentration. If the mineral veins separate from the rock cleanly, then processing workers can concentrate the ore by taking advantage of the greater weight mineral compared to the rock.
The methods used in the processing of copperleadzinc ore could be classi fied as follows (Bulatovic, 2007): a) sequential copper, lead, zinc flotation method where the copper, lead, and zinc are sequentially floated to produce separate copper, lead and zinc concentrates, .
Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, ... The nonlead metals are usually sold to other metal processing plants. The refined lead ...

offers 341 lead ore processing equipment products. About 51% of these are mineral separator. A wide variety of lead ore processing equipment options are available to you, such as gravity separator, flotation separator, and sprial separator.
There is an old method, called the Parkes process, which was used to separate silver (and gold) from lead. The argentiferous galena is first reduced to metallic lead, Then zinc is added to the molten lead, The silver is much more soluble in the zinc. The zinc rises to the surface, taking most of the silver with it.
Lead processing. Approximately 30 percent of all lead consumed is in the form of lead compounds, such as oxides, tetraethyl and tetramethyllead, lead chromates, sulfates, silicates, and carbonates, and organic compounds. These lead compounds have been used in paste mixtures in storage batteries, in cements, glasses, and ceramics,...
The separation of metallic zinc from its ores by pyrometallurgy is much more difficult than with other common metals, such as copper, lead, and iron, because the reduction of zinc oxide by carbon (C) proceeds spontaneously only above the zinc boiling point of 907 °C (1,665 °F).
History of Lead Smelting. The process of creating lead can be traced back to 6500 Lead was created by dumping lead ore inside a furnace along with charcoal. However, it seems as though the lead was not used that often in the ancient past. The main problem was that it is too soft to be used to create a structure or forge weapons.

Separation of copper and lead is the main problem of copper and lead zinc flotation process. This process can retrain lead and flotate copper, also can restrain copper and flotate lead. Whether which one plan is good, should be determined by specific test.
HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of preconcentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity.
mineral . The results of a gravity separation of Itakpe (Nigeria) iron ore by jigging indicated that the iron recovery increased with decrease in particle size . This present study investigated the response of Baban Tsauni (Nigeria) leadgold ore to jigging separation, multigravity and shaking table separation.
processing are taken over by what is known as separation. Regardless of the method or methods used, the aim is always the same to take a natural aggregate of minerals (an ore) and separate it into two or more mineral products. In general, the products of separation are: 1) the concentrate which contains the valuable minerals; and 2)
The zinc content of mined ore is usually between 3 and 10 percent. Almost all ores contain the lead sulfide mineral galena and small quantities of cadmium sulfide. Chalcopyrite, and copperiron sulfide, is often present. The most common gangue constituents are calcite, dolomite, and quartz.
