and actually retrofitted their plants with AG/SAG mills. Historically, the most widely used method to establish the AG/SAG grinding requirements for processing an ore from a deposit was to obtain bulk samples, each weighing 10 to 100 tons, and grind them in a test grinding mill having a minimum diameter of about 5.5 feet. These programs can
Is it advisable to use a SAG mill for small, say 2000 TPD concentrator operations? The processing, in this case, is a complex zinc/tin mineral and we are afraid a SAG would P80 produces too much fines (since the tin is to soft brittles) (tin cassiterite).The mineral is marmatite and casiteritre
It is essential that the ore be tested to determine its amenability to AG/SAG milling, the grinding power requirements, optimum milling conditions, and grinding circuit arrangement. These are conducted on a representative sample of ore at the test plant in York, PA. For most ores, small samples (about 100 pounds) are adequate to
