LEAD REFINING. Lead refining is no different, except that while refining we do a lot of value addition to the crude ore. In our process of refining we use a Pyrometallurgical process for producing Lead with a purity level of %. We supply refining Kettle furnaces of various capacities ranging from 5 – .
Concept note on secondary copper smelter in Saudi Arabia. Introduction Proposal envisages setting up a Copper Smelter with Copper waste and scrap as the raw material in two phases – Phase I and Phase II. The plant will graduate progressively into a cluster in Phase III using profits from the initial seed investment of around 120 illion.
