The QSL, or Queneau-Schuhmann-Lurgi, process treats all grades of lead concentrates, including chemically complex secondary minerals, in a refractory-lined reactor into which oxygen and natural gas are blown through tuyeres at the bottom. The green, or unroasted, charge is first oxidized in a molten bath by the submerged oxygen injection; this produces a flue gas carrying oxides of lead and
The ore concentrating process requires pine oil, alum, lime, and Potassium Amyl Xhantate. Limestone or iron ore is added to the lead ore during the roasting process. Coke, a coal distillate, is used to further heat the ore. The manufacturing process of lead ingots. 1 mining the ore 2 Concentrating the ore 3 Flotation 4 Filtering 5 Roasting the ore 6 Blasting
The concentrate is sintered before being smelted in to produce a 97% Lead concentrate. The Lead is then cooled in stages which cause the lighter impurities (dross) to rise to the surface where they can be removed. The molten Lead bullion is then refined by additional smelting with air being passed over the Lead to form a slag layer containing any remaining impurities and producing 99.9% pure Lead.
Brief About Lead Ore/Concentrate Lead is a soft, malleable, ductile, bluish-white, dense metallic element, extracted chiefly from galena and found in ore with zinc, silver and copper. Whilst it is still used for its malleability and corrosion resistance, it is now its chemical properties that make it

Most ores contain less than 10% lead. Ores are crushed and concentrated by froth flotation typically to 70% or more. Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silicates of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a coke-fired blast furnace.

Lead Ore Concentrate Lead Ore is a mineral and natural compounds formed through geological processes. Galena(PbS) is most common form of available Lead Ore..
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, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is

Although lead (Pb) rarely occurs naturally in its elemental state, it has been used by man throughout history. One reason for this is that its principal ore, lead(II) sulphide known as galena, is easily recognised and readily reduced by heating with charcoal.
structure of an O&C. While lead compounds (soluble forms) are indeed classified in the EU under the Dangerous Substances Directive5 and now EU-CLP only the (bio)available fraction in the mineral structure should be taken into account for a relevant classification of O&Cs. 2. Hazard identification and classification of ores and concentrates
First, What Are Lead Ore Minerals Or Lead Concentrates? Lead ore minerals are rocks containing lead, which is a heavy metal that is denser than most common materials. The lead within the rocks are soft and malleable, and also have a relatively low melting point. The lead concentrate is the pure lead extract from the rock (ore) itself.
