For base metal smelting and refining projects, our smelting and refining group offers a globally recognized and respected team who can work in close collaboration with you to provide novel technical solutions to pressing challenges.
refining process, by-products such as gold and silver are collected as slimes that are subsequently recovered. Sources of wastewater include spent ... The smelting process typically produces less than 3 tons of solid waste per ton of copper produced. Pollution Prevention and Control.
content of the dust at primary lead smelting and refining facilities. Tables 12.6.1 and 12.6.2 present particulate, PM-10, lead, and SO 2 emission factors for primary lead smelting.
Melting and Refining There are numerous ways to melt glass depending on the desired product, its end use, the scale of operation, and the prevailing commercial factors. The glass formulation, raw materials, melting technique, fuel choice and furnace size will all depend on these factors (IPTS/EC, 2013. p. 40).
Leading Chinese and international zinc industry experts will be invited to report on the latest process and equipment developments in zinc smelting, refining and recycling. Special attention will be given to environmental protection strategies such as the effective utilization of the leaching residue generated during zinc smelting.
Tin smelting furnaces are one of three basic types: reverberatory furnaces, blast furnaces, or electric furnaces. Usually the operation is carried out as a batch process. The principle of tin smelting is the chemical reduction of tin oxide by heating with carbon to produce tin metal and carbon dioxide gas.
Slime generated in the electrolytic refining process contains precious and rare metals such as gold, silver, slenium, tellurium, etc. These precious and rare metals are recovered through processes in the slime treatment plant.
Hoover and Strong has invested in a new refining process known as the "Miller Process". Bullions from smelting are melted in a furnace. Chlorine gas is then bubbled through the liquid metal, turning silver and base metals into solid chlorides.
