Industrial applications of new sulphur bio

Hydrogen sulphide is emitted into the environment as dissolved sulphide in wastewater or as H2S in natural gas, biogas, syngas or refinery gases. Waste streams containing sulphate are generated by many industries, including mining, metallurgical, pulp and paper and petrochemical industries.

Pollution problems in the metallurgical industry: A review

2021-6-21  At the beginning of this century, the metallurgical industry used to emit waste gases directly at ground level (For example, the roasting of sulfide ores or the making of coke by the beehive method). Later on, stacks were built only high enough to provide adequate draft for furnaces. Operations were usually established in isolated areas. As the scale of operations increased and as lands near industry
