The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left “hand”. There are two methods of identifying the “hand” of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.
shows the sample tree flowsheet. Two ores were evaluated via this sampling technique. The first sample was a low-grade gold ore (about 5 g/t gold) mill feed sample from a South African gold mine. The particle size was 95% -12 mm. The second sample consisted of boulders of high-grade gold ore (about 60 g/t) that were crushed to yield a 95% -12 ...

Grab sampling usually consists in taking portions of ore at random from muck piles, chutes, or the tops of cars of ore. When done in this manner it is a haphazard method that can be relied upon only for roughly approximating the grade of the ore and often is employed merely for that purpose.

Sampling is defined as taking a small portion of a whole mass that accurately represents the whole mass. Very simple to define, however obtaining a representative sample is anything but simple. Mathematicians will say sampling is expressible as a series of mathematical equations. Such as, for sampling "X" pounds of material, one would take "y ...

The theory is that by capturing the sample midstream, after purging a large volume of oil (40 to 50 percent) from the sump prior to filling the sample bottle, the sample taken more closely resembles a sample representative of the system. One problem associated with this engine oil sampling procedure is the difficulty of extracting the sample.
Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants.
