"longitude": "145.099069", In metallurgy, the first process is crushing and grinding of ores into a fine powder in a crusher or ball mill, which is the first step in the manufacturing process. The oxidation of lead to lead monoxide results in the formation of lead dioxide. Sulfide ores are separated using a process known as froth flotation, which involves dissolving the crushed ore in a solution of water, pine oil, and detergent. The process of magnetic separation is utilised when the ore's and impurities' magnetic characteristics are not the same.
