The arsenic content of Rosebery copper flotation feed is mainly present as arsenopyrite (FeAsS), containing approximately 46.0% arsenic with the remainder of the arsenic in copper sulphosalts (tennantite (CuAsS)), in a solid solution series with tetrahedrite (CuSbS).
Sep 17, 2013· Recovered from stibnite associated arsenic (gold) mineral technology program is twofold: First, at pH = 6.5, the use of copper sulfate, lead nitrate as an activator, black drugs and xanthate as collector for antimony, Arsenic (gold) flotation, concentrate mixed with sodium carbonate, sodium sulfide slurry to adjust the pH to 11, suppressing ...
the fundamental principle of flotation froth flotation, also known as flotation, is the result of minerals deposited on the outer bubble (bubbles mineralization) float to the top of the slurry, and then to the intent sorting and gangue minerals. Why some cIt is a high technological enterprise that integrated research, manufacture, sales and service .
The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible.Extractions are low and the solutions soon become 'foul.' The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.
Consequences of roasting gold ore: Water quality – high As Arsenic in sediments increases during time of active mining and emission controls. Similar pattern shown for Cu, Sb, Zn and Pb. Concentrations 4x higher in vegetated area due to trapped fines. Some As released from sediments migrates up and is recaptured in surface Fe oxyhydroxides.
Jan 27, 2012· Antimony occurs in tri‐ (+3) and pentavalent (+5) compounds and is found in the Earth's crust mostly associated with sulfur as stibnite and in ores associated with arsenic. Antimony is a group VA element of the periodic table and it has many of the same chemical and biological properties as the element arsenic.

USA - Selective flotation of cubanite and ... Table 2 shows the solids content, and copper and nickel recovery data, for the underflow stream from the copper rougher flotation. 1.97 pounds of lime per ton of dry ore fed was added to the underflow stream to activate the nickel and residual copper, raising the pH of the stream to 7.9.
The invention discloses a flotation separation method of antimony sulfide and gold-bearing pyrite. Sodium hexametaphosphate is adopted as a dispersing agent, sodium silicate is used as a silicon and calcium gangue inhibitor, copper sulfate is used as an antimony and gold mineral activating agent, butyl xanthate is used as a collecting agent, and No. 2 oil is used as a ing agent, so that ...

A two-stage roasting process, similar to that used for arsenic sulfide ores, can also volatilize antimony oxides and prevent adverse reactions such as the production of metallic antimony, which can coat the surface of gold particles (Nagy et al., 1966) or the formation of silver glasses in high-silver ores (Matsukawa and Sakai, 1956).
A proprietary gold recovery process has been adopted to quantitatively and selectively recover gold from complex alkaline sulfide solutions containing a mixture of metals such as arsenic, tin, mercury and antimony. This is illustrated by selectively removing gold from an alkaline sulfide leach solution containing these impurities. The assay of
gold is commonly associated with the sulfides of antimony arsenic copper iron and silver.3 . amalgamation froth flotation and cyanidation. . gold and silver are dissolved by cyanide in solutions of high ph in the presence of oxygen. . heap leaching because the material must be removed from the vat at the end of the.
Gold recovery cyanide process is widely used. A professional gold recovery industry that handles high-sulfur, high-arsenic, and other refactory gold concentrates, the arsenic grade is about 10%. The high-sulfur and high-arsenic gold concentrate is pretreated by two-stage roasting, and the two-stage roasting sand is leached into the gold recovery cyanide process by sulfuric acid leaching.
Arsenic and antimony do present a larger problem, by reacting with the cyanide and using up all of the excess oxygen, leaving little or no oxygen to effect the dissolution of gold. Carbonaceous gold ores can have the carbon adsorb the gold onto its surface, and as a .
This gold processing method is suited for the quartz vein type gold-bearing oxidized ore which with uneven disseminated grain size and high oxidation degree, the gold-bearing ore basically free of copper, arsenic, antimony, etc. 3. Flotation process

Despite the preliminary extraction of antimony from the flotation concentrate, gold recovery remains at a fairly low level and, according to various data, does not exceed 30-40% [ [6]].Gold ...
Due to the high content of arsenic and antimony, the traditional flotation-roasting-cyanidation process was not suitable. The direct cyanidation gold extraction for the raw ore was 44.70 %.
Copper concentrates with high arsenic contents must be pretreated before conventional smelting to prevent environmental pollution with arsenic compounds. In this work, experimental results concerning the selective removal of arsenic and antimony from copper concentrates are presented.
Ph In Flotation Antimony High Arsenic Gold. Extracting antimony from high arsenic and gold containing 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 ...
Epigenetic mineral deposits in the Tintina Gold Province are generally characterized by high concentrations of arsenic and antimony in their mineral assemblage. A total of 347 samples (ground water, surface water, and stream sediment) were collected to investigate the distribution and mobility of arsenic and antimony in the environment near known mineral deposits.
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.
