Process description Primary zinc is produced from ores which contain 85 % zinc sulphide (by weight) and 8–10 % iron sulphide, with the total zinc concentration about 50 %. The ores also contain metal sulphides such as lead, cobalt, copper, silver, cadmium and arsenic sulphide. The ores are oxidised with air giving zinc oxide, sulphur oxide and zinc ferro. Chlorine and fluorine are ...

Secondary risks to nontarget terrestrial vertebrates are lower when compared to primary risks because zinc phosphide does not accumulate in target pests. Secondary risks to wildlife and domestic animals can mostly result from nontarget animals ingesting dosed animals with undigested zinc phosphide. Label restrictions reduce the probability of significant exposure .
