For the purposes of this chapter, the severing of precious metals and the further acts or processes necessary to separate, refine, or finish the product are construed to be a continuous and uninterrupted process, and the tax imposed by this chapter shall apply to the value of the finished product. If the processes of refining, finishing, or smelting are carried on by a different person than mined or severed the ore or product from its natural state, the tax shall apply to the value of the finished product and the amount payable by each part engaged in the production shall be allocated by the secretary of revenue by a computation of the value of the product in each state of production. The total tax so allocated may not exceed the total percent to be collected.
