Instead of using industrial driers, the solution was to adapt the iron ore transfer chute as a drying chamber. The chutes are closed equipment where the change in direction of the conveyor belts is made, which take the iron ore from the yard to the ship.
How to Extract Refractory Gold Ore Using Gold Recovery
The higher the moisture content of the pickling residue, the more the total amount of impurities entering the gold recovery cyanide process. In order to minimize the moisture of pickling residue, the main measures adopted in gold recovery cyanide 12 LABORATORY SAMPLE PREPARATION,Moisture loss is also observed when samples containing occluded water are ground and crushed. The process ruptures some of the cavities, and exposes the water to evaporation. More com-monly, the grinding process results in an increase in moisture content due to an increase in surface area available for absorption of atmospheric water.

Heap leaching Wikipedia
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to theCARGO LIQUEFACTION AND DANGERS TO SHIPS,The moisture content of a cargo beyond the flow moisture point (FMP) may liquefy .
