Direct Chlorination Of Carbon By Copper Chloride In A

Feb 25 copper chloride changed its chemical state during rising temperature these chemical states of copper played three types of roles first a twostep dechlorination at around 300 c the reduction of cucl2 to cucl and 400 c the oxidation cucl to cuo and chlorination of the carbon matrix

Primary Metal Production

For example many ores that contain native copper have arsenic compounds associated with them when the ore is melted the molten copper dissolves the arsenic as a result the metal from the furnace can be less pure than the ratio of coco 2 needed for reduction when using carbon as a reducing agent there will be a minimum ratio of co to
