Crushing is performed in stages using a combination of jaw, cone and impact crushers and is performed dry. The material is moved by mechanical means with conveyor belts. Sometimes the blasting and crushing fines are washed off the ore, and pumped as a slurry directly to the grinding circuit.

Flotation. Flotation is also called reverse settling, since sediment moves upward and thus against gravity. Rising gas bubbles adhere to solid particles, which make them lighter than the must and cause them to rise to the surface. A fining agent such as gelatine coats the particle and aids flock formation.

I find flotation is best used minimally. It''s better to focus on crushing+sorting and the combining recipes. I normally do flotation+leeching for one of the ores, Bobmonium IIRC, to get a broad range of ores, crystallization to get niche ores (like titanium, gold, etc), and focused recipes for everything else.
