Lead production statistics – ILA. While it has a high economic value, lead is relatively economical to produce As with all metals, there are two main production routes Primary production from mined lead ore is of course the original source of all lead, but secondary production, where it is recovered from recycled products or from residues arising from the production process is of enormous ...

2014-4-25 Lead is a very soft and toxic metal with very high density. Lead has been used widely since historic times. The earliest report of its use dates back to 6400 BC in the modern day Turkey. Commercial production of lead was started in 17th century. Lead is commonly available together with zinc in ore along with other metals such as silver and cadmium.

2011-12-1 The lean zinc oxidized ore was firstly ground to a size below 0.2 mm, followed by alkaline leaching at 90 °C for 120 min in NaOH solution, in which both zinc and lead are effectively extracted. Lead concentrates were then highly selectively and quantitatively produced from the leach solution by adding sodium sulfide as precipitant.
