Explain the process of crushing the ore in metallurgy.
After the ore gets crushed, it's then ground using various types of grinding machines to reduce the size of the particles further. The ore is ground into a fine powder-like substance, which helps in the efficient extraction of the metal in the subsequent stages of metallurgy. The degree of crushing and grinding required depends on the type of ore.
