Process for refining copper in solid state
Fire refining The advantages of the process of removing impurities before smelting become particularly significant when the fire-refining stage is considered. The main objective of fire refining is to eliminate impurities such as arsenic, antimony, bismuth, and others, by means of oxidation and slagging.
Kinetic study of solid phase demineralization by weak acids …
We describe a one-step bio-refinery process for shrimp composites by-products. Its originality lies in a simple rapid (6 h) biotechnological cuticle fragmentation process that recovers all major compounds (chitins, peptides and minerals in particular calcium).The process consists of a controlled exogenous enzymatic proteolysis in a food …
