I gleaned this from Ken Reser.. ...when deciding which Molybdenum mines product will be most readily marketable at premiun value. When Moly is marketed for Alloying or Catalyst Markets it must first be Roasted. When it has certain impurities from it's source such as Copper or other Sulfides ie; Pyrite, Chalcopyrite, Galena etc., it must undergo more intensive processes in order to be usable for Specialty Steel and Catalyst Markets. This involves 'leaching' out the Sulfides after Roasting & then washing & re-drying the product. This is costly, time consuming and can mean the difference between the Roasting process costing $0.75 /lb and $5.00 /lb. And that in reality affects the mines profitability as it's concentrates will demand less value in the market. This is one reason why a so called 'Primary Moly' mine like Endako's product, even tho low grade but with 'Clean' Molybdenum is in such demand. Endako is at present the only Primary Moly Mine in Canada. Massive low grade Porphyry Primary Molybdenum deposits can usually produce Moly the cheapest. In a Moly by product mine such as a Copper Mine, then expensive secondary curcuits must be added to recover the Moly and the higher costs of the finished product after Roasting is somewhat offset by the initial Cu production. In the ever changing world of Molybdenum it appears to many industry experts that the age of the Primary Molybdenum Mine is upon us.
