Explanation

Gold is commonly mined through the alluvial process, also known as placer mining. This method extracts gold from riverbeds and stream deposits where gold particles have settled due to their high density. Coal requires underground or open-cast mining, sulfur occurs in mineral veins, and zinc is typically extracted from sulfide ore deposits.
