To put it another way, textbooks tell us that for ordinary gold ore, the size of the largest piece of rock in the sample determines the weight of sample needed. ... A sheet-iron caisson 18 or 24 inches in diameter ...
Stopped-belt sampling is the reference method for collecting ore samples against which other sampling procedures may be compared. Sampling from moving streams is the preferred method. Sampling from stationary situations should only be considered when sampling from moving streams is not possible.
Sep 15, 2006· The iron ore industry is an important segment of the world economy. The main mineral oxides are magnetite and hematite. The composition of iron ore playsan important role in both the iron (blast furnace) and steelmaking operations. Sampling is done both at the source and at the destination. Sampling protocols and preparation are described.

Sampling is the most important procedure in arriving at the value of an ore. Improper sampling makes other procedures, including assaying, valueless, as the sample must truly represent the ore from which it is taken. Before sampling, clean fresh faces must be exposed in order to prevent the possibility of salting. Having taken a large representative sample by chiseling 3″ to 6″ wide and 1 ...
