Copper and Antimony Recovery from Electronic Waste by

A strategy for the efficient recovery of highly pure copper and antimony metals from electronic waste (e-waste) was implemented by the combination of hydrometallurgical and electrochemical processes. The focus is on copper recovery as the main component in the leached solution, whereas the antimony recovery process was established as a purification step in order to achieve a highly pure copper

Antimony Recovery from End-of-Life Products and Industrial

Feb 08, 2016 Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and

Can you separate tin and antimony from range scrap

What is wrong with range scrap as is? In many cases it is about ideal, or at least it is for me. nothing wrong with it persay, i just don't need the hardness since im powder coating, so if i can recover the tin and antimony and use it in batches that arnt going to be powder coated, its like free tin/antimony.

Lead smelting Wikipedia

Lead scrap includes lead-acid batteries, cable coverings, pipes, sheets and lead coated, or terne bearing, metals. Solder, product waste and dross may also be recovered for its small lead content. Most secondary lead is used in batteries. To recover lead from a battery, the battery is broken and the components are classified.

Recycled Antimony Market Global Industry Report, 2030

Antimony recycling is a process of converting battery scrap into reusable material. Secondary antimony is primarily derived from spent lead-acid batteries. Antimony recycling is an alternative to "conventional" waste disposal that can reduce primary metal consumption and greenhouse gas emissions. Battery scrap offers various advantages.

Lead processing Refining Britannica

Lead processing Lead processing Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used
