ABSTRACT

Arsenic is a particular element whose properties make it equally desirable and undesirable depending on the field of application or the process involved or related to. Arsenic trioxide, one of the common compounds of arsenic is classified as a suspected human carcinogen, a cause for certain types of cancers. However, it has beneficial effects in other fields such as in wood preservation, agricultural chemicals etc. Similarly arsenic metal is slightly poisonous but it is also beneficial since it is primarily used in the manufacture of lead alloys for use in lead-acid batteries. Arsenic is rightly a cause for concern in non-ferrous smelting metallurgy but its extraction as a by products might be beneficial. As a result industrial and feasible technologies for arsenic extraction play an important role. In this paper, in order to have a clear picture of the state-of-the art of the past and present of arsenic metallurgy the authors review several industrial technologies used for extraction of arsenic as a by-product or in other ways. Some bench scale technologies or other recently proposed extraction technologies are also reviewed.
