ISO 7834:1987(en), Iron ores ? Determination of arsenic

This International Standard specifies a molybdenum blue spectrophotometric method for the determination of the arsenic content of iron ores. This method is applicable to a concentration range of 0,000 1 to 0,1 % ( m / m ) (1 to 1 000 ?g/g) of arsenic in natural iron ores, and iron ore concentrates and agglomerates including sinter products.

Arsenic Ores | Article about Arsenic Ores by The Free

Arsenic ores are divided into several known types according to the commercial classification of ore deposits: arsenic (arsenopyrite and realgar-orpiment), gold-arsenic, complex-metal-arsenic, copper-arsenic, arsenic-cobalt, and arsenictin ores. Commercial ores contain a maximum of 2 percent As, but ores with a 5–10 percent As content are
