and the lime consumption was 1.4 pounds in addition to the pounds used in the flotation circuit.While copper is a trace element that occurs naturally in plants and animals copper sulfate is not and can act as an irritant when someone is exposed to it. Crops and agriculture are cleaned after being treated with copper sulfate and there's minimal risk to ingesting it from a treated crop as it primarily binds itself to soil sediments.INVESTIGATING COPPER SULFIDE CONTAMINATION IN A FAILED LARGE GSU TRANSFORMER Lance Lewand,
