germanium ore crushing
Shadowlands Mining Profession and 1-150 Leveling Guide
Shadowlands ore has two types of mining deposits: Normal and Rich. Rich deposits can yield up to three times as many Ore or Stone as a Normal deposit, though are very rare. Yields also depend on Mining skill, as well as the RNG. You will get lower yields at lower levels, so it can pay to use any +Mining items you can get.

Discovery of Three Elements Predicted by Mendeleev's Table
From then on, production of gram quantities of gallium became almost routine (at least for Lecoq) and he and his colleagues, by crushing several hundred kilograms of ore and treating it with 1500 L of aqua regia, succeeded in producing as much as 75 g of the element by 1878 . Lecoq remarked that gallium constituted a very small percentage of ...

Mineral Resource of the Month: Germanium
Germanium is never found as a pure metal in nature, but trace amounts occur in many minerals, including common metallic ore minerals such as the zinc mineral sphalerite. Zinc smelters produce the majority of the world's supply of germanium. Germanium is also recovered from fly ash produced by the burning of certain types of coal.
