Byproduct

A byproduct or byproduct is a secondary product derived from a production process, manufacturing process or chemical reaction; it is not the primary product or service being produced.. A byproduct can be useful and marketable or it can be considered waste: for example, bran, which is a byproduct of the milling of wheat into refined flour, is sometimes composted or burned for disposal, but in ...

Heavy Metals

Cadmium is produced as an inevitable byproduct of zinc (or occasionally lead) refining, since these metals occur naturally within the raw ore. However, once collected the cadmium is relatively easy to recycle. The most significant use of cadmium is in nickel/cadmium batteries, as rechargeable or secondary power sources exhibiting high output, long life, low maintenance and high tolerance to ...

What is Rhodium and Why is it So Valuable?

 · There are many reasons for this: the primary reason being rhodium content in the earth's crust is extremely rare, and the metal is mined as a byproduct of platinum and palladium mining or nickel mining. There is no such thing as a primary rhodium mine, and the major producers are all loed in South Africa. South Africa produces over 85% of the global rhodium supply annually, with majority ...

Don't Cut Threads — Form 'Em

 · Unlike thread cutting, no material is removed during thread forming. Rather, the process displaces the material to generate the thread form. Since the metal's structure is cold worked along the thread profile, the threads produced are generally stronger and have a smooth, burnished surface finish.

How copper is made

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased. Some of these steps are conducted at the mine site itself, while others may be conducted at separate ...
