Arsenic Minerals Education Coalition

DescriptionRelation to MiningUsesArsenic (As) is classed as a semi-metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur.

ENARGITE (Copper Arsenic Sulfide)

Enargite is related to the rare mineral wurtzite. Wurtzite is a zinc sulfide with a formula of ZnS. In enargite 75% of the zinc atoms are replaced by copper and 25% of the zinc atoms are replaced by arsenic, Cu3AsS4. The similarity is easier to see if wurtzite's formula is rewritten as Zn4S4. The different elements however do not lend

Arsenic in Copper Concentrate

2019-10-15  Copper concentrates recently tested for mineralogy both measured about 0.44 percent arsenic content. This is above typical levels where penalties occur. Tennantite and enargite as well as Freibergite are copper arsenic sulphide minerals that respond to flotation in a similar manner to other copper sulphides.

Arsenic: Mineral information, data and localities.

Name of early origins from the Greek αρσενικόν ("arsenikon"), "masculine", alluding to its potent properties. The Oxford English Dictionary lists the first record of the word "arsenic" in a 1310 book concerning orpiment de iiij libris de orpiment venditis, of unknown authorship.

Arsenic Minerals Education Coalition

Most arsenic is obtained not from an ore mineral of arsenic, but as a by-product in the treatment of gold, silver, copper, and other metal ores. Environmental laws require that arsenic be removed from ores, so that it does not enter the environment in effluent gases, fluids, or solids.

TENNANTITE (Copper Arsenic Sulfide)

Tennantite forms a series with the much more common mineral tetrahedrite (Cu12Sb4S13, Copper Antimony Sulfide). The two share the same crystal structure but they differ in the percentage of arsenic versus antimony. Antimony rich specimens are tetrahedrite while arsenic rich specimens are tennantite.

Recover Metal from Acid Leach Processing of Arsenic

2019-10-21  Arsenic, copper, and molybdenum were effectively removed from arsenic-bearing flue dust using a three-stage continuous sulfuric acid leach. Leach conditions to maximize arsenic and copper extraction while minimizing bismuth extraction were determined: 25-wt pct H2SO4, 20- to 25-wt pct solids, a leach temperature of 55° C, and a 30-min residence time.

Unlocking Value in Copper Arsenic Sulphide Resources

2015-11-20  [9]. The pressure hydrometallurgical approach to processing high arsenic bearing copper concentrates is a favorable option as mineral extraction and arsenic fixation can take place in a single autoclave vessel. Under CESL pressure leaching conditions (150°C, 1380kPa) high copper extraction and arsenic fixation as scorodite is possible.

Bioleaching of Arsenic-Bearing Copper Ores

2018-2-10  World copper (Cu) production has been strongly affected by arsenic (As) content, because As-rich Cu concentrates are not desirable in the metal foundries. When As-rich Cu concentrates are processed by smelting they release As as volatile compounds into the atmosphere and inside furnaces, generating serious risks to human health. In recent years, exports of Cu concentrates are being
