Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The first method of metallurgy is crushing and grinding. The ores occur in nature as huge lumps. They are broken into small pieces with the help of crushers and grinders. These pieces are then reduced to fine powder by using a ball mill or stamp mill. This process is known as pulverization.
