Chapter 2. Background

a ball mill at a feed rate of 90 tons per hour. As shown in Table 2.3, the mineralogy of the western and the eastern ore bodies is not very different from that of the ore bodies A and B. The feed composition includes 20-40 g/t of silver and the average iron content of the sphalerite (in solid solution) is in the range of 3-6% (Reyneke, 2000).

Brown Bear Mine – Western Mining History

Gold was associated with pyrite and galena. The ore was mined from timbered stopes between raises 20 feet apart. Four men produced about 18 tons of ore per day. The ore was hauled in trucks to the mill at the Watt adit portal, where it was crushed to one-half-inch in a jaw crusher and ground to minus 75- mesh in a 42- by 48-inch ball mill.

Mineral processing

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.
