Mineral Concentrate Marketing
· Lead, zinc and copper smelters each having different smelting practices either give a low return, no payment or a penalty for metals adverse to the particular process. For instance, copper contained in a lead concentrate is paid for at or near the price paid for lead while lead in a copper concentrate will return less than 50% of lead price.
