The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

Scrubbing is by means of mechanical force and between the sand grains grinding and peeling force to remove the dressing method of quartz sand surface film, adhesive and mud iron impurity minerals, it can further smash these mineral aggregate monomers, and then by the classification process to remove impurity mineral mud.
Iron bacteria will use even small amounts of iron present in the ferrous state, oxidize it, and then use the energy. Manganese is also used by other bacteria to form organics, which contribute to the iron bacteria slime in the well and/or water system. Iron bacteria are found any where a food source of iron is available. The presence of one
This water is reused to wash and transport sand (steps 5 and 6). An important step in processing frac sand, which occurs offsite for this operation, involves drying and sorting the sand into grainsize ranges to meet industry needs. The sand is then shipped out of state by rail or barge.
