Question

what do you mean by pulverisation?
also explain hydrometallurgy.​

Answer 1

Answer:

pulverisation is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size.

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involves the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. This process is used in extraction of less electro positive or less reactive metals like gold and silver.
