The two main problems of ore genesis are the origin of metals and the process(es) of emplacement. Lead isotopes have proven to be a powerful tool for studying these questions. We have studied Pb-Zn mineralizations from Montagne Noire and Cevennes (southern Massif Central, France) by means of lead isotopes.

One way of concentrating the ore is by chemical separation. For example, the separation of aluminium (Al) from the bauxite ore. This process of separating aluminium from the bauxite ore is also termed Bayer's Process. Hot NaOH reacts with the bauxite ore which leads to the formation of sodium aluminate which is water-soluble.

Base metal oxides can often result in slag bound values (it has been happening to me with with ore off of my claim). Here is what I've learned: 1. If the ore has either cupric or cuprous copper it will demand 1.8:1 and 1.5:1 litharge to convert it to a fusible oxide state. Base metal oxides consume lead oxide as they become fusible.
