The South African gold mining industry has a legacy of abundant tailings dams, which have attracted the attention investors because their potential as cheaper secondary resource. In this we investigate study recovery from refractory calcine dam. Bulk mineralogy indicated silicates and iron oxides to be most phases. Scanning Electron Microscopy (SEM) showed exist in submicrometre micrometre size...

The recovery of gold from refractory ores and concentrates is a significant problem in the modern processing industry. use bacterial oxidation technology at Navoi Mining Metallurgical Combine (Uzbekistan) made it possible to increase share recoverable during Kokpatas Daugyztau deposits. However, operation biological installation, arose abundant foaming reactors. This article devoted issue bioox...

This article explores the novel gold nanoparticle-enhanced photodynamic therapy of methylene blue against recalcitrant pathogenic Candida albicans biofilm. Physiochemical (X-ray diffraction, ultraviolet-visible absorption, photon cross-correlation, FTIR, and fluorescence spectroscopy) and electron microscopy techniques were used to characterize gold nanoparticles as well as gold nanoparticle-me...

Most gold deposits occur associated with sulphides like pyrite and arsenopyrite; thus, precious metal dissolution is possible by oxidizing auriferous sulfide concentrate using simultaneous pressure oxidation cyanidation. The effectiveness of this process extraction can be influenced the temperature, cyanide (NaCN) concentration, oxygen pressure. In study, we conducted experiments to characteriz...

The discovery of the iron-regulatory hormone hepcidin in 2001 has revolutionized our understanding of iron disorders, and its measurement should advance diagnosis/treatment of these conditions. Although several assays have been developed, a gold standard is still lacking, and efforts toward harmonization are ongoing. Nevertheless, promising applications can already be glimpsed, ranging from the...
