Nontoxic technology extracts more gold from ore. Study shows new chloridebased process recovers 84% of gold compared to the 64% recovered with traditional methods. Gold is one of the world's
Chlorine is generated during iron ore sintering, mostly in the form of alkali chlorides and primarily accumulates in sintering dust, which must be removed before reusing. In this study, an insitu monitor leaching system based was designed to detect chloride ion water leaching behaviors in realtime and improve the understanding of
An insitu monitor leaching system based on chloride ion selective electrode was set up to examine the leaching behaviors of chlorine in realtime (Figure1). A certain amount of iron ore sintering dust was added into deionized water in 1.0 L Bunsen beaker and stirred
摘要： For the recent 15 years, Institute "Gipronikel", in collaboration with Kola MMC specialists, have developed the methods of process flowsheet of electrolyte nickel and cobalt production, based on chlorine leaching of various ore feed types, such as ore
Abstract—Extended tests of alumina fluid chlorination are performed. The implementation of the chlorine technology is possible when using alumina, which has a high reactivity with chlorine. The improved nepheline technology for obtaining such an oxide is proposed: nondesilicated aluminate liquors undergo carbonization followed by
About 97 % of the chlorine and nearly 100% of the caustic soda in the world are produced electrolytically from sodium chloride, while the rest of the chlorine is manufactured by the electrolysis of KC1, HC1, chlorides of Ti and Mg, and by the chemical oxidation of chlorides .The electrolytic technologies currently used are mercury, diaphragm, and ionexchange

Chlorine plays a central role for the industrial production of numerous materials with global relevance. More recently, polychlorides have been evolved from an area of academic interest to a research topic with enormous industrial potential. In this minireview, the value of trichlorides for chlorine storage and chlorination reactions are
This study illustrates the extraction of fluoride (F−) and chloride (Cl−) from noncombustible inorganic iron ore matrix by employing steam distillation (SD)based volatilization process followed by ion chromatographic (IC) determination. This costeffective, simple and green sample preparation setup involved decomposition of sample matrix in

The salts are recycled through electrolytic cells to produce sodium or magnesium for reuse in metal reduction and chlorine for reuse in chlorination of the ore. A different process that offers hope for an improved and simplified method of producing titanium metal is the direct electrowinning of titanium from TiCl 4 in fused chloride salt baths

Chlorination Process for Gold. This process was based on the fact that chlorine, in the presence of moisture, converts gold into the trichloride AuCl3,which is soluble in water and removed by washing, the gold being then precipitated by ferrous sulphate, sulphur dioxide, hydrogen sulphide, or charcoal. Coarse gold requires long
MicrocystinLR (MCLR) is a potent hepatotoxin that is often associated with blooms of cyanobacteria. Experiments were conducted to evaluate the efficiency of the chlorine/UV process for MCLR decomposition and detoxification. Chlorinated MCLR was observed to be more photoactive than MCLR. LC/MS analyses confirmed that the
