Environmental Code of Practice for base metals smelters

Environmental Code Of Practice For Base Metals Smelters

Roasting is the conventional technique used in the pyrometallurgical processing of copper, nickel, and zinc sulphide concentrates. During roasting, the sulphur is removed by adding air and simultaneously heating and drying the concentrate to achieve sulphur content favourable for smelting. The sulphur is released as sulphur dioxide.

Dust Control for Seed Separation and Processing RoboVent

Dust Control For Seed Separation And Processing Robovent

Dust control is important to reduce the spread of microbial pathogens through the seed separation and processing supply chain. Uncontrolled dust on surfaces can become a breeding ground for dangerous yeasts, molds and bacteria. If this dust is allowed to re-contaminate seed processing lines, pathogens can end up in the final product.
