Good points. There is often more to proper stockpile operation than meets the eye. Degradation and water infiltration can cause handling difficulties, as well as the processibility changes that you mentioned, acid runoff etc, so one needs to understand what happens to that material as it sits long term.

2020-5-8They sometimes used mercury, which forms an amalgam with small particles of gold and silver. Miners used mechanical crushing and grinding machines to break up ores for further processing. Early miners used Mexican arrastras or stamp mills, which reached their peak in the late nineteenth century, to crush ores into sand-size particles.

2020-5-1The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...

The Hercules Pickaxe is an Iron Pickaxe enchanted with Efficiency IV and Unbreaking II. What is unique about this Pickaxe, is that it can crush ores into their corresponding Dusts. For example, if you break an Iron Ore, you will get 2 Iron Dust. This means instead of putting together an Ore Crusher, the pickaxe does all the work for you.

2020-5-4To determine the amount of gold metal in ore, there are two kinds of gold assay adopted. The dry assaying method i.e. by fusing the powdered ore with or without fluxes. The wet assaying method i.e. by the agency of liquids. In the principal wet assay, the ore is thoroughly dissolved in acids, and, by the addition of reagents, precipitates containing the metals are thrown down.
