The pretreatment of an antimonial refractory gold and silver ore was investigated using alkaline sulphide leaching The ore assayed 20 g/t Au and 220 g/t Ag and contained predominantly quartz/clay
Apart from the environmental concerns regarding the toxic nature of arsenic and antimony De Michelis et al 2013 these elements promote a refractory behavior in ore samples Fraser et al 1991
Where gold is associated with arsenic antimony tellurium and certain other minerals it is often only partly soluble in cyanide solution The difficulty is Gold Extraction from Carbonaceous Ore The so called graphite or carbonaceous mineral that exists in certain ores in California Montana West Africa and western Australia has
The mineralogical characterization of antimony bearing refractory gold concentrates and the antimony extraction by ozone in HCl solution were investigated Zhengyuan Gold Mine [J] Gold 2005 26 12 36∠39 in Chinese [18] WANG Ji kun LEI Ting Treating low grade antimony ore by bath smelting continuous fuming process [J
Pyrite is a dominant gold carrier in many types of ore deposits according to previous works [2 3 10 88 101] In pyrite gold can be present either as visible grains [1 4 5] or as invisible
Antimony bearing gold ore is a common refractory gold is often wrapped in antimonite and other sulfide ores due to the presence of antimony the extraction rate of gold is often low when leaching by the traditional cyanide of
Gold containing antimony ore is a type of refractory gold in which gold is intimately associated with stibnite Guo et al 2017 When the traditional cyanidation method is used for gold extraction thioantimonate by stibnite decomposition reacts with oxygen to form antimony acid salt or antimony
Slurry electrolysis was also presented to extract antimony from high arsenic and gold containing stibnite ore to produce cathode metal antimony Zhang et al 2019 In general hydrometallurgical
For example a gold concentrator processes typical iron gold ore with a processing capacity of 200 tons/day and a gold grade of 10 grams/ton All ores are calcined in a rotary calciner The calcined ore is transported into the percolation tank with a mining cart
Bau gold mining district located near Kuching Sarawak Malaysia is a Carlin style gold deposits Geological analyses coupled with remote sensing data were used to detect hydrothermal alteration rocks and structure elements associated with this type of gold mineralization Image processing techniques including principal components analysis linear
This was a geometallurgy exercise in which 8 lithologies from the same open pit gold deposit were tested for Silver and Gold Extraction and evaluation of the response for 2 Processing Methods The feed gold and silver was amenable to gravity separation and flotation
Hypochlorite leaching system is a strong oxidizing solution for metal sulfides which are naturally associated with gold extraction This study evaluated the hypochlorite leaching of refractory gold ore by using the response surface method central composite design RSM CCD as a statistical approach in determining the optimum condition of gold extraction from
The Solubility of Antimony Sb in Liquid Hydrocarbons and Its Implication for the Ore Forming Process of Orogenic Antimony Gold Deposits in Southern Tibet January 2024 Minerals 14 2 141

Wei Y Dou X L Ju L P et of antimony in gold antimony ore and antimony ore by inductively coupled plasma atomic emission spectrometry with four acids dissolution[J] Rock and Mineral Analysis 2013 32 5 715 718 Google Scholar [6]
This work aims to shed light on the leaching kinetics of antimony from stibnite ore in potassium hydroxide KOH solution Response surface methodology based on central composite design was used to investigate the effect of time temperature solid to liquid ratio S/L and KOH concentration as independent parameters on the leaching efficiency of antimony
Iron oxide copper gold ore refers to the symbiosis of copper ore and gold ore in gold ore in some form Its amount is about 10 million to 4 billion tons IOCG ore contains copper with a grade of % to 5% and gold with a content of to grams per ton
A wet chemical process was developed for the separation of gold from gold bearing antimony sulphide ores The ore sample was taken from the mine Urquidi from Oruro in Bolivia It contained roughly 33% Sb in the form of antimonite 24% Si in the form of quartz small quantities of Pb Fe Cu and Ni as well as 63 g/t gold 60% of it as visible gold
In 1884 A Bobierre and others proposed for the first time the volatilization roasting method for antimony regulus extraction In 1896 electrolytic antimony was produced Since 1930 antimony ore melting in blast furnace became an important process for producing antimony metal
In order to overcome this problem Yang et al utilized the sodium sulfide to extract the antimony from refractory gold ore and the leaching recoveries of antimony and arsenic were % and 0
The challenges associated with gold extraction involve various types of refractory gold ore The ore is refractory if the gold recovery through cyanidation is less than 80% [3] Carbon sulphide and tellurium ores are the three types of gold refractory ores [4] Gold with physical encapsulation is the most common refractory ore This is due to
