Study on Surfactants for Passivation of Naturally Occuring Carbonaceous Matter in Gold Bearing Ores
The naturally occurring carbonaceous material (CM) in gold bearing ores often exhibits strongpreg-robbing properties. It can adversely affect the process of gold recovery during the cyanidation due to its ability to adsorb, or preg-rob gold from the cyanide leach solution. Treatments of carbonaceous ores with chemical surfactants as blinding agents to limit pregrobbing have shown promising resu...
متن کاملLeaching of gold ores with high cyanicides: a physico-chemical modeling approach
Processing of gold ores with high sulfide minerals is problematic as they consume cyanide and reduce gold leaching. Optimization of gold leaching and cyanide consumption requires a methodology to estimate the amount of exposed cyanicides, their leaching kinetics, and speciation of cyanide complexes that consume the free cyanide and compete with gold. In this paper, a physico-chemical approach i...

15 صفحه اولRituximab for Treatment of Hemophilia A with High-Responder Inhibitors
Background: The development of inhibitors is a complication factor replacement therapy in hereditary factor VIII deficiency. Several management options are available for the treatment of inhibitor. Rituximab, a monoclonal antibody against CD20, reduces inhibitor level in rare bleeding disorders. The aim of this study was to evaluate the effectiveness of rituximab in lowering or eliminating the ...
متن کاملA two-stage bacterial pretreatment process for double refractory gold ores
Double refractory gold concentrates were subjected a two-stage microbial process to destroy both sulfides and carbonaceous matter. In the first stage, the well-known sulfide biooxidation process, which utilizes chemolithotrophic bacteria was used to oxidize sulfides and in the second stage carbonaceous matter is destroyed using the bacterium Streptomyces setonii. After biooxidation of sulfides ...
