7.3: Implementing the Sampling Plan - Chemistry LibreTexts

Aug 10, 2020  A reduction in particle size is accomplished by crushing and grinding the gross sample. The resulting particulates are then thoroughly mixed and divided into subsamples of smaller mass. This process seldom occurs in a single step. Instead, subsamples are cycled through the process several times until a final laboratory sample is obtained.

11.23 Taconite Ore Processing

Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.

Crushing and grinding the sample The first important point is the sampling. The size, and nature of material chosen should be enough to represent the sample mass of interest. For fine-grained samples, this may be only 200 - 500 g, but for coarse grained samples it is not unusual to begin with 10 - 15 kg.
