Author Description

Excerpt from Testing for Metallurgical Processes In considering the treatment of gold-bearing ore, it is usually necessary to obtain sufficient data to fully answer the following questions: (1) What is the value of the ore? (2) Is the ore free milling? If so, what percentage of the gold can be amalgamated? (3) What value has the tailing after amalgamation? Can it be further treated at a profit? (4) What per centage of concentrate does the original ore carry? Can the ore be profitably concentrated or could the tailing from the amalgamating plates be better treated by other methods?
