• Hybrid sulphur cycle for in-situ supply of hydrogen and oxygen to copper plant. Process models a refinery the hybrid in Aspen Plus. Techno-economics green refinery. Potential lower carbon dioxide emissions from production Copper is third-most widely-used metal worldwide. However, processing an energy-intensive process consuming large quantities fossil fuels, both as reducing agent energy whic...

Use of biomass as alternatives to petrochemicals has attracted a broad range of scientific and industrial interests. We propose here a novel environmentally-friendly recycle system for precious metal ions such as gold and platinum ions using protein-rich biomass. My keynote lecture is composed of three pieces; (1) selective adsorption of precious metal ions onto proteins, (2) the mechanism stud...

The practicability of a pyrometallurgical scheme for raw material processing is established as result the analysis methods intended to dearsenate and process gold-arsenic concentrates well equipment execution. conceptual design vacuum without forced movement dispersed in sublimator reaction zone materials proposed. In-process tests sublimation arsenic sulfides from gravity flotation received Ba...

1.1 Manufacturing processes Major industries with exposure to strong inorganic acid mists include those that manufacture phosphate fertilizer, isopropanol (isopropyl alcohol), synthetic ethanol (ethyl alcohol), sulfuric acid, nitric acid, and lead batteries. Exposure also occurs during copper smelting, and pickling and other acid treatment of metals (Suresh, 2009). Minor uses of sulfuric acid i...

The objective of the project is to examine the potential use of wool as an industrial and/or laboratory adsorbent. This will be carried out by examining the metal sorption and desorption behaviour of a series of wool powders using radiotracer probes. Wool powders will be prepared using various milling techniques, and their metal-binding properties investigated using radiotracers such as Co, Cu ...

Specific gravity, refractive index, acid value, saponification peroxide moisture content, smoke point are properties evaluated. metals analyzed include; Lead, Nickel, Copper, Iron, Arsenic, Iron. Total w...

Nowadays, in the given conditions of Uzbekistan, there is hardly any comprehensive technology either for processing industrial waste or extraction rare and precious metals at JSC “AGMK” with small amounts metals. The presence man-made containing platinum, palladium rhodium AGMK indicates that plant can manage industry, having been several years without recycling ore. This article discusses feas...
