Evaluation of the Cyanidation Leaching of Gold in a Waste Rock Ore
Samples of the waste rock obtained from Marofengin South Africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. The results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, ...
متن کاملA fuzzy-based prognosis of ore mineralization potentials in Ramand region (Qazvin province)
The Ramand region is a part of the magmatic belt in Urmieh-Dokhtar structural zone in Iran, located in the SW of BuinـZahra. This area mainly consists of felsic extrusions such as rhyolites and rhyodacites. Argillic alterations with occurrences of mineralized silica veins are abundant in most of the volcanic units. In this research work, we used the GIS facilities for modeling the Ramand geo-sp...
متن کاملSynthesis of gold nanoparticles: a new approach in using a nanoporous membrane in conjunction with ultrasonication
Gold nanoparticles were synthesized by chemical reduction of HAuCl4 inside the pores of a polycarbonate-based membrane followed by dissolving the membrane in dichloromethane and further sonication. Sonication time as the main affecting factor on the nanoparticle size was investigated. The characterization by transmission electron microscopy showed the formation of gold nanoparticles with diamet...

متن کاملAcute mercury poisoning and mercurial pneumonitis from gold ore purification.
We describe four men who had symptoms of acute mercury poisoning following exposure to mercury vapor. They were attempting home gold ore purification using a gold-mercury amalgam and sulfuric acid. Three of the four patients required treatment with penicillamine. The clinical and laboratory data are presented along with pulmonary function test results. Long-term follow-up of one patient indicat...
