Mineral Processing Laboratory Equipment Countless installations have proved that operating profits can be increased by installation of a well planned ore dressing laboratory. The basic function of a laboratory is to provide, rapidly, accurate data on metallurgy that can be closely reproduced in the plant.
White to no streak, clear to white to pink color, H=2, used for wallboard. pale yellow streak, six planes (but generally all planes are not visible), often twotoned blackgold in color, H=, odor of sulfur when scratched, used for zinc ore. (ZnS), can be either metallic or nonmetallic.
Nonmetallic Mineral Resources; There are metals that are hard which conduct electricity and heat with characteristics of luster or shine. Such metals are called metallic minerals. For example Silver, Chromium, Tin, Nickel, Copper, Iron, Lead, Aluminum, Gold, and Zinc. Characteristics of Metallic Minerals. Metallic Minerals show a metallic shine in their appearance.
46th ©Annual Canadian Mineral Processors Operators Conference, Ottawa, Ontario, January 2123, 2014 INTRODUCTION Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented (Stehr, 1988). The year 1948 saw the successful application of Du Pont's "sand mill" for pigment grinding.
