copper refining wastes

Copper Scrap

Very pure copper scrap, usually manufacturing wastes, is melted and cast as ingot copper or alloyed and cast as brass or bronze. Less pure scrap is usually fire- and electrorefined for all uses. Alloy scrap is melted and cast as new alloy, often sweetened with new metal (e.g., Cu, Zn, or Sn) to bring it to its desired composition.

Industrial Process Description

 · Blister copper, containing a minimum of 98.5% copper, is refined to high-purity copper in two steps. The first step is "fire refining," in which the molten blister copper is poured into a cylindrical furnace, similar in appearance to a converter, where first air and then natural gas or propane are blown through the melt to remove the last of the sulfur and any residual oxygen from the copper.

Environmental Cost of Refineries

Refining processes also often use harsh acids and bases to separate the desired metals from the wastes, which can harm the environment by themselves when they change soil and water chemistry. For example, some fish can only live in water within a narrow pH range, and some plants only flower within a certain pH range.This can have far-reaching effects on agriculture and livestock, as well as on ...
