zinc ore arsenic

Arsenical bronze

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 arsenic.

Behavior of arsenic in hydrometallurgical zinc production

Keywords: arsenic, arsenopyrite, zinc concentrates, roasting, leaching. INTRODUCTION Arsenopyrite (FeAsS) is the most common mineral of arsenic sulphides. The arsenic amount in the zinc concentrates varies within wide limits (0.001–0.88%)1. When the content of arsenic is high, a large part thereof is oxidized to As 2 O 5 2.
