Mineral Processing. The mined ore is crushed and milled before the flotation process to desired grain size. Crushing is done in two phases followed by milling in the bar and ball mills. The flotation process is conducted in the stages. The first stage is the silver-gold-lead flotation which is followed by the zinc-silver flotation and pyrite

Crushing/grinding is typically the machining technique used in the first instance with freshly mined/quarried rocks, ores and minerals. Tolerant of large sized ‘raw’ input materials, crushing can be thought of as a cruder technique than milling for example, as it produces comparatively larger sized output products; such as aggregates for construction and infrastructure building, small to
