Leaching is defined as which process?

Explanation:
Leaching is the process of dissolving soluble substances from a solid material by a liquid moving through it or soaking it in a solvent. In mining and hydrometallurgy, a solvent percolates through ore or waste, carrying dissolved minerals away as a liquid. That’s why naming the process itself is the correct choice. Other terms are related concepts or unrelated ideas: leachants are the liquids used to drive the leaching, not the process itself; Liquefied Petroleum Gas is simply a fuel, not a dissolution process; and a Lost-Time Accident is a safety term about injuries, not leaching.
