pH values, at the same time making possibilities of the increased recovery of the antimony and gold and decreasing of the arsenic appearing, contemporary protecting the environment. Also, these laboratory experiments have enabled to prove the optimum conditions of the process of bulk flotation on the appropriate pH-value.
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 .

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.
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).
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 %.
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 ...
Jul 01, 2011· Gold mostly concentrates in high-sulphidation systems at 300 °C at low pH (<2) and high log f(O 2)(–28). For example, the concentration of Au in the vapor phase is 0.06 ppb at pH = 2 and log f(O 2) = −28 (Archibald et al., 2001). Under the condition of the same oxygen fugacity but at pH = 1, the Au concentration is 0.6 ppb.
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 ...
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.

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 ...
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).

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.
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.
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.
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 ...
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 .
The ideal leaching time was defined as that needed to extract enough arsenic such that a high extraction of gold would result from the cyanidation of the oxidative leach residue. The overall results indicate that the best leaching conditions for extraction of more than 90 pct arsenic were 2M NaOH, 100° C, 40 psig, 100 g/L ore, and 4 to 7 h.

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.
