A systematic review of sustainable gold extraction from …
The gold-bearing ore was heated as a thick slurry of ore, air, water and limestone in large pressure chambers. The slurry interacted with thiosulfate and a fine, bead-like material that collects the gold. At full capacity, 13,400 tons of ore can be processed daily, with leaching taking place simultaneously in two sets of seven tanks.
Iron Ore Pelletizing Process: An Overview | IntechOpen
This chapter aims to provide an overview and the evolution of iron ore pelletizing process including: 2. Pelletizing process and raw materials. The iron ore is mined mostly from open pit deposits through mining operations and the raw product, "run of mine," is subjected to mineral processing.

Mineral vs. Ore: What's the Difference?
In essence, not all minerals are ores, but all ores contain minerals. Ores are classified based on their metal content and the feasibility of extracting that metal. This means that the economic value of the metal and the cost of extraction are key determinants in defining an ore. 8. For instance, aluminum is extracted from the mineral bauxite.
