Selective Removal of Arsenic from Copper Concentrates ...
· Arsenic bearing minerals such as enargite (Cu 3 AsS 4) are a rich source of copper. Enargite contains 48 wt% of copper, compared to chalcopyrite (CuFS 2 ) which contains 34 wt% copper. In addition, any separation of arsenic bearing minerals from copper ones will result in some copper nonarsenic bearing species reporting to the high arsenic concentrate.
An effective separation process of arsenic, lead, and zinc ...
· Separation of arsenic and valuable metals (Pb, Zn, Cu, Bi, Sn, In, Ag, Sb, etc.) is a core problem for effective utilization of high arseniccontaining copper smelting ashes (HACSA). This study developed an effective separation process of arsenic, lead, and zinc from HACSA via alkali leaching followed by sulfide precipitation.

Trace Metals Analysis
Trace metals analysis allows detection and identifiion of low levels of metals in a sample which can be critical to product development, quality control and regulatory compliance. Determining trace levels of metals in samples can also help to identify contaminants and provides important data to help both process improvement and chemical ...
ARSENIC AND ARSENIC COMPOUNDS
Arsenic and arsenic compounds were considered by previous IARC Working Groups in 1979, 1987, and 2002 (IARC, 1980, 1987, 2004). Since that time, new data have become available, these have been incorported in the Monograph, and .
Selective Separation of Cu, Zn, and As from Solution by ...
· The selective precipitation and flotation of copper, zinc, and arsenic ions from dilute aqueous solutions were investigated. Phase separation was accomplished effectively by the dissolvedair technique for the production of fine gas bubbles, and a shortchain xanthate was applied as the collector for copper ions, dialkyldithiocarbamate for zinc, and ferric sulfate for .
Chapter Arsenic
Arsenic appears in nature primarily in the form of sulfides in association with the sulfides of ores of silver, lead, copper, nickel, antimony, cobalt and iron. Trace amounts of arsenic are found in soils and other environmental media. Arsenic is mainly transported in the environment by water. In oxygenated water, arsenic usually
Copper(II) arsenate
Copper arsenate hydroxide or basic copper arsenate (Cu(OH)AsO 4) is a basic variant with CAS number . It is found naturally as the mineral olivenite. It is used as an insecticide, fungicide, and miticide. Its use is banned in Thailand since 2001. See also. Lead arsenate; Calcium arsenate; Paris Green (copper acetoarsenite)
