Method for removing essentially all of the chemically bonded arsenic and antimony from copper sulfide ores. The arsenic and antimony are selectively leached out using Na 2 S in a basic solution. The resulting Na 3 AsS 4 and Na 3 SbS 4 are converted to the sulfides or to ferric arsenate and ferric antimonate for safe disposal. Sodium and sulfur values are recovered for recycling in the process.
Bullantco N.L. and Emu Nickel N.L.6.22 Мб The gold in the stibnite concentrate represents most of the „floatable free gold‟ in the ore plus the gold locked in the stibnite mineral matrix.The study results indicate that a high-grade stibnite concentrate containing 62% antimony and ~1oz/t gold with recoveries of 92.2% and 47% respectively.
Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb2S3) …
Abstract Cyanidation tests on two ore samples from two different gold deposits are reported. The first sample contained 10.5 ppm gold with high arsenic and antimony. The second sample had a low gold content (2.5 ppm) but a high silver content (160 ppm). The first series of test work focused on the determination of conditions for extracting gold from the samples ground to − 75 μm.

Aug 26, 2021 Epithermal gold deposits are among the richest gold deposits in the world, with some bonanza-grade ore shoots containing more than 1000 g/t gold-equivalent or a kilogram of gold for everyone tonne of rock mined. The tonnage of ore in epithermal veins is typically smaller than other types of low-grade gold deposits.. Gold mineralisation within epithermal veins can occur over vertical …

Jan 10, 2020 Antimony-bearing sulfide gold ore refers to the antimony-bearing sulfide or gold ore in which antimony minerals exist independently. This type of ore is generally difficult to be extracted by amalgamation and cyanidation directly, so flotation, roasting, and cyanidation gold extraction processes are often used to extract this type of gold.
Mar 09, 2017 Entrusted by the owner in QInghai, Shandong Xinhai Mining Technology & Equipment Inc. carried out mineral processing test and study on the gold-antimony ore. With Au content of 7.5g/t, as content of 0.86% and Sb content of 0.34%, the ore was belong to refractory ore. Based on the ore characterizes, and compared flotation process and cyaniding ...
Jan 25, 2020 The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels.
On the pages I have images of native gold and platinum plus a variety of different ores for gold, silver and copper, plus info about these ores and where they are found. Mark Twain's Prospecting Adventures Young Sam Clemens (later to be known as Mark Twain) came to Nevada and contracted a very bad case of Gold and Silver Fever .

Jun 15, 2021 Soil sampling has revealed high gold anomalies (up to 3.75 g/t Au) along with spatially associated antimony which is thought to be from the mineral stibnite which forms a …
charge material of copper concentrate mixed with a siliceous flux (often a low-grade copper ore) is heated in air to about 650 C (1200 F), eliminating 20 to 50 percent of the sulfur as sulfur dioxide (SO2). Portions of impurities such as antimony, arsenic, and lead are driven off, and some iron is …

Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.
Jun 25, 2021 The average annual metal production during the first four years of operation is expected to be approximately 463,000 troy ounces of gold and 18.4 million pounds of antimony per year.

Jun 01, 2019 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.
Gold fineness is lower than quartz-sulphide gold + copper ores and may be extremely variable within any one deposit (e.g., Mt Kare; Corbett and Leach, 1998). Thus some, particularly higher level, carbonate-base metal gold deposits are silver rich and one, gold deposits are silver rich and one, Bowden’s Find, constitutes a carbonate-base metal ...
