More than 60 minerals contain some form of lead, but only three are usually mined for lead production. The most common is called galena. The pure form of galena contains only lead and sulfur, but it is usually found with traces of other metals in it, including silver, copper, zinc, cadmium, and antimony as well as arsenic.

According to the International Lead Zinc Study Group, refined zinc production reached 12.8 million tons (or about 28 million pounds) in 2013. The ten largest zinc producers accounted for just over 5.8 million tons or 45 percent of the world total. The ten largest refiners include both companies

The mines of Rajasthan have given definite evidence of zinc production going 80–90% zinc, with lead, process based on zinc and zinc
an electrothermic process. This annual production level 3 to 11 percent zinc, along with cadmium, copper, lead, for the production of zinc or
The Imperial Smelting process is based on the reduction of zinc and lead into metal with carbon in a specially designed Imperial Smelting furnace. The IS process is an energy intensive process and thus became very expensive following the rise of energy prices.
Lead processing: Lead processing other investigators led to commercial production of lead acid storage by the Parkes process, which consists of adding zinc to
2 Zinc can be produced by a process called froth flotation, which is also used for reduction of copper and lead ores. This process involves grinding the zinc ore to a fine powder, mixing it with water, pine oil, and flotation chemicals, and then agitating the mixture to float the zinc to the surface.

The well established two stage sequential flotation process is employed: An important first step entails ensuring the sphalerite surface is not activated with dissolved metal ions, which then makes the sphalerite non floatable. The established lead zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion
The commercial production of electrolytic metals had its origin a century ago when James Elkington, an English electroplater, invented a process for refining copper electrolytically; later, about 1890, aluminum was first produced on a commercial scale by electrolysis, followed by lead in 1905, nickel in 1910, and zinc about 1915.

I do not like lead in the zinc for a number of reasons, one of which is that leaded zinc attacks cast iron excessively and some of the zinc coating falls off into the molten zinc. I now have 28 kettles using my process with excellent results all using no lead.
Zinc is the 23 rd most abundant element in the earth's crust. Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc is necessary to modern living, and, in tonnage produced, stands fourth among all metals in world production being exceeded only by iron, aluminum, and copper.
The purpose of this study was to update the average environmental impacts of global primary zinc production using a life cycle assessment (LCA) approach. This study represents the latest contribution from zinc producers, which historically established the first life cycle inventory for primary zinc
