Arsenical bronze Wikipedia
Copper ore is often naturally contaminated with arsenic; hence, the term "arsenical bronze" when used in archaeology is typically only applied to alloys with an arsenic content higher than 1% by weight, in order to distinguish it from potentially accidental additions of arsenicArsenic removal from copper ores and concentrates through alkaline leaching in NaHS media The arsenic dissolution behavior of other copper ore and concentrate samples were investigated while Fullston D, Li C, Ralston JSeparation of enargite and tennantite from nonarsenic copper sulfide minerals by selective oxidation or dissolutionArsenic removal from copper ores and concentrates Arsenic may also be obtained from copper, gold, and lead smelter flue dust as well as from roasting arsenopyrite, the most abundant ore mineral of arsenic However, arsenic is not recovered from these sources Arsenic in the mining industry The Role of Arsenic in the Mining Industry
Arsenic in Copper Concentrate
In a certain case study of “high” Arsenic in Copper Concentrate (almost 05% As) produced by flotation, and where the Cu Conc is mostly chalcopyrite and therefore the main form of copper; the content of secondary copper minerals was variableArsenic ores are divided into several known types according to the commercial classification of ore deposits: arsenic (arsenopyrite and realgarorpiment), goldarsenic, complexmetalarsenic, copperarsenic, arseniccobalt, and arsenictin oresArsenic Ores Article about Arsenic Ores by The Free Arsenic is probably partly oxidized and volatilized as arsenious oxide The elimination, however, is less marked than in calcining ores, in which the arsenic is mainly present in minerals associated with the copperore, but not in combination with the bulk of the copperHow to Remove Arsenic, Antimony Bismuth from Copper
Arsenic removal from copper–silver ore by roasting in
In the copper–silver ore, arsenic exists in compound tennantite (Cu 12 AsS 13) In fact, tennantite is an unstable substance at high temperature according to , in oxygen presence and Reaction (1) on anaerobic condition Many other ore bearing arsenic substances react similarly, such as arsenopyrite (FeAsS), (Cu 3 Arsenic is found in the smelter dust from copper, gold, and lead smelters, and is recovered primarily from copper refinement dust [39] On roasting arsenopyrite in air, arsenic sublimes as arsenic(III) oxide leaving iron oxides, [36] while roasting without air results in the production of gray arsenicArsenic Wikipedia2642007 Abstract The processing of gold bearing sulphide minerals which contain arsenopyrite and other complex arsenic sulphide minerals results in arsenic containing emissions and effluents which must be given careful consideration in relation to clean air and clean water standards The sources of arsenic and the various process options for Arsenic in Gold Processing: Mineral Processing and
Rejecting arsenic from copper ores IOM3
‘Each ore will have a different window depending on which copper and arsenic minerals are present,’ explains Bruckard The process produces separate lowarsenic and higharsenic concentrates The lowarsenic substance can be sold off to smelters at no penalty, while the higharsenic product is roasted at about 700ºC in a fluid bed reactorArsenic removal from copper ores and concentrates through alkaline leaching in NaHS media The arsenic dissolution behavior of other copper ore and concentrate samples were investigated while Fullston D, Li C, Ralston JSeparation of enargite and tennantite from nonarsenic copper sulfide minerals by selective oxidation or dissolutionArsenic removal from copper ores and concentrates Arsenic is probably partly oxidized and volatilized as arsenious oxide The elimination, however, is less marked than in calcining ores, in which the arsenic is mainly present in minerals associated with the copperore, but not in combination with the bulk of the copperHow to Remove Arsenic, Antimony Bismuth from

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 tennantiteWhat is an ore of arsenic?
