Grinding and polishing is the final stage in the metallographic sample preparation process and consists of several steps. Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformation-free, scratch-free and highly reflective sample surface. The sample may need to be examined, either etched or unetched, to
Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (m) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used
Stone mills are ideal for the milling of spices, because of the low milling temperature, thus preventing discoloration and loss of flavor, and its ability to grind the product extremely fine. Many varied applications requiring fine milling with low oil and moisture content is routinely supplied, from macadamia nut shells to starch.

GRAVITY RECOVERY OF GOLD FROM WITHIN GRINDING CIRCUITS
choice for recovering gold from within grinding circuits. These are usually installed in the mill discharge, cyclone feed or the cyclone underflow streams where a fraction, typically 10-40%, of the stream is treated by the gravity circuit. The key factors affecting
Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the
