Separation practice of copper arsenic sulfide ore ...

Separation practice of copper arsenic sulfide ore. The separation of copper and arsenic is mainly to solve the separation problem of copper minerals and arsenopyrite, which can be summarized as follows: (1) Highly selective collector. It is very important to enlarge the separation of the two minerals by using selective collectors.

Arsenic Ore Dressing Separation Jaw Crusher Manufacturer

Many other ore bearing arsenic substances react similarly, such as arsenopyrite FeAsS, Cu 3 AsS 4. It is known that oxygen pressure is a crucial condition to arsenic removal. The low pressure in vacuum is a good anaerobic condition. This is the basic principle for the separation of arsenic from tennantite.

Oct 19, 2007  In order for the high-arsenic regions of the Northparkes copper–gold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of high-arsenic drill cores from Northparkes it was possible to selectively separate tennantite ...

Dearsenization of copper ore by high gradient magnetic ...

In this study, the possibility of dearsenization of copper ore using a high gradient magnetic separator was investigated. (2) Since the separation point of copper ore is smaller by one digit than waste phosphor, it is difficult to recover 5 μmparticles, but the relationship is similar. (1) There is no copper-free arsenic ore in the concentrate ...

arsenic antimony separator

Its characteristics are compared with a conventional hydride generator for the determination of arsenic, antimony and tin by using flame atomic absorption spectrometry. This simple hydride generator combines hydride production and gas-liquid separation in one unit, obviating the use of a separate mixing/reaction coil and gas-liquid separator.
