This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.
Some prospectors are interested in the methods of processing sulfide ores to extract their values. The two of the best known processes are smelting and roasting. The two are actually different methods, but both involve heating the ore to high temperatures.

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
Jun 01, 2019· Antimony extraction reached over 98%, the average extraction of Fe, As, and Au were 5.50%, 1.14%, and 0.63%, respectively. Gold and aresenic remained in the leaching residue, which was further used as a raw material for gold extraction. Thus, the separation of antimony from gold and arsenic was achieved.
The bacteria feed on nutrients in the minerals, causing the metal to separate from its ore. The metals commonly extracted using this process include gold, silver, zinc, copper, lead, arsenic, antimony, nickel, molybdenum cobalt, and uranium.
which makes it possible to obtain 10–12% antimony concentrates during the extraction of Sb, and 90% within the next floatation using xanthogenate. This is 20% higher than with the application of flotation methods alone. Gold antimony ores contain 1.5–2.0 g/t Au and 1– 10% Sb (mainly Sb 2S 3); associates are FeAsS and FeS 2. Schemes of the ...
In the post-medieval period parting using antimony, sulfates and mineral acids was also used. In the modern period chlorination using the Miller process, and electrolysis using the Wohlwill process are the most widely used methods of refining gold by removing silver and platinum. These latest processes have been employed for over 100 years.

Jan 01, 2011· 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 and barite, and to a lesser extent, sulphides such as pyrite, stibnite, sphalerite, zinkenite (Pb9 Sb 22 S 42) and andorite (Sb 3 PbAgS 6).
I myself use this method to extract from many contaminated things. I don't even bother separating the gold from the objects, I just completely put the objects in a bath & dissolve everything. Them I just separate / precipitate everything out in the refining process. You can even put different carat of gold into the one solution via this method.
and gold production facility with capacity of up to 50,000 dry tonnes per annum of antimony concentrate, producing up to 20,000 tonnes of antimony and 60,0 00 ounces of gold (Tristar, 2018).
History. The smelting of gold began sometime around 6000 - 3000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote on the subject. According to de Lecerda and Salomons (1997) mercury was first in use for extraction at about 1000 BC, according to Meech and others (1998), mercury was used in obtaining gold until the latter ...

Dec 05, 2019· The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it's hazardous to both your health and the environment to use them.
The 'cathodic corrosion' technique, using water, salts and electrodes, creates cation-stabilised metal anions from which nanoparticles form. 'We recently found that we could use the method to remove metals such as gold and platinum from printed circuits of .
Sep 01, 2020· According to Midas Gold, the company hoping to both mine and restore the brownfields site, the Stibnite Gold Project will produce over 100 million pounds of antimony.
Using an ore containing 3.3 per cent, antimony, partly sulphidic and partly oxidised, the average anthracite consumption was 15 to 20 per cent, of the charge, of which 5 to 8 per cent, was used as reducer and 10 to 12 per cent, as fuel.
Apr 23, 2012· both antimony and gold containing sulphides) and then, subsequently, using flotation to extract an Sb-rich concentrate from the bulk concentrate. Both approaches have provided positive results. The sequential flotation approach has the benefit of extensive on-site operating experience and its development is the most
