The results of investigations of hydrometallurgical opening of the rest copper gold sulfide concentrates with sulfuric acid are presented. It is shown that processing of flotation concentrates by concentrated (90%) sulfuric acid (with solid liquid relationship as much as 14 15) during 5 6 hours at 225 176;C provides 96 97% copper extraction in the soluble state.
May 27, 20160183;32;This subject is a little off the topic of this website but Im trying to get some feedback on a technology I have been working on the past few years that was focused on remediation of toxic waste. I believe it has an application to recover gold from sulphide ores by eliminating the current roastin

Sulphide Gold Ore Treatment by Leaching and Flotation Process Problem with gold recovery from sulphide ore How may a mill get the maximum recovery of gold from a sulphide ore , at the least capital cost and at the same time obtain the highest net return.
Jan 23, 20120183;32;Step 7 Processing (on site) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low grade ore is relatively simple while higher grades require more extensive processing. Step 8 Refining (off site)
method for processing the refractory sulfide ore is the method of hydro chlorination along with thiocar bamide. As a method of processing the gold containing tailings of the refractory sulfide concentrates we chose the method of electrochemical oxidation of sulfides in the ore pulp with the use of various chlo

Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earths crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions
Platsol Process. The Platsol process was originally developed in collaboration with the University of British Columbia, Kane Consultants , and Lakefield Research in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and was tested on similar types of concentrate materials.

Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the Merrill Crowe zinc precipitation process and the other is the adsorption of the gold onto activated carbon.
Refractory gold processes. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or
Well, sulfides, selenides and tellurides are simply minerals which contain sulfur, selenium, and tellurium combined with some metal. Unusually this is the metal we are interested in, but sometimes other valuable metals can be mixed in as trace elements. An example of this is when gold

Copper Mining amp; Extraction Process Flow Chart. This is the same process for both copper and molybdenum porphyries. The smelter is basically a large furnace which melts the concentrate and drives off the sulfide to leave molten copper metal this is still contains impurities and it needs to be refined further to make it a salable product.
Free gold is that which can be easily liberated and is unbound to other minerals. Free gold can be rapidly recovered in high amounts using gravity concentration methods. Traditionally, simply exploiting the high specific gravity of free gold for recovery required little energy and was profit generating.
Sulfides are the most common member of this mineral grouping and most prospectors have seen them at one time or another. The familiar quot;fools goldquot; is iron pyrite. Pyrite, galena, sphalerite, and chalcopyrite are all common sulfide minerals that are found in many precious metal veins and other hard rock deposits.
gold ores. We at Hazen Research have had the opportunity to participate in the development and application of a number of gold ore processes and to review others' results from applying processes to gold ores. This experience gives us the background necessary to compare the available processes on their technical merit.
Sulfide ores, such as chalcopyrite, sphaelerite, galena, and pyrrhotite, and mixtures of these ores have historically been found with micron size gold particles included in them. This generally involves frother, several collectors (promoters) and possibly some modifying or depressing agents as well.
Processing Sulfide Ores. Historically, miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls. However, with the implementation of the Mercury Export Ban of 2008 and the high costs of installing equipment to prepare sulfide ores for cyanide leaching,
Corvus Gold Inc. 2 April 27, 2017 NR17 5 Continued hosts a large oxide resource. In addition to the higher grade, millable sulfide material, Corvus is conducting tests of sulfide leaching for heap leach applications, similar to the test work conducted
This is a concern because Arsenic is actually very common in many gold ores. Selenium, mercury and other toxic elements are also found in many high sulfide gold and silver ores as well. To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you don't want to melt them.
Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite, where it occurs in both the chemically bonded state and as nano size grains of metallic gold. During roasting or pressure oxidation, the sulfide matrix is destroyed and essentially all the gold
Sulfide Quartz Gold Deposits Hodgson (1993) cited a body of evidence developed by Goldfarb and others (1986), Hamilton (1988), Hoffman (1990), and Kerrich and Wyman (1990) in which formation of low sulfide quartz gold deposits are associated the prograding of arc trench complexes at convegent plate margins. The model developed for the process of
Apr 14, 20140183;32;If your processing a high sulphide content gold ore this will not work. With high sulphide gold ore break it down and seperate it till all you see is the yellow shiny stuff then take that and put it into a hydrocloric acid solution and let it sit for a week or so swirling it in bottom of container occasionally.
Regrinding of pre concentrated non refractory sulphide complex gold material, by a conventional regrind mill, can produce free gold particles. This improves the amount of gold that can be recovered by further processing using equipment such as the InLine Leach Reactor.
