 >Propose a chemical procedure to extract cobalt from the mineral cobaltite, CoAsS. What are some of the hazards of such a procedure? 


Expert Answer

Step 1

The mineral Cobaltite has Co, As and S with it. Using chemical procedure called roasting Co is extracted from given mineral.

Step 2

During this roasting of mineral with oxygen sulfide is converted into oxide and SO2 is separated as gas with the arsenic oxides as volatile material. The equation is as follows,
