Ball Mill an overview | ScienceDirect Topics
Ball mills give a controlled final grind and produce flotation feed of a uniform size Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills (dry basis) is typically 75 vol% ore and 25% steelBulk flotation The flotation stage consists of multiple steps, usually running through rougher flotation cells, then cleaner column cells, and often scavenger cells which work together to give a high total yield of the bulkSeparating moly from copper: flowing through the
Flotation an overview | ScienceDirect Topics
Flotation feed is generally the ball mill cyclone overflow but in cases where some of the valuable minerals are liberated at coarse sizes and are recirculated in the cyclone underflow, these can be recovered before overgrinding by treating the cyclone underflow by flotation2016年10月16日· When the time of contact of some of the reagents cannot be controlled accurately enough by their addition to the ball mill, a conditioning tank is installed between the grinding and the flotation sections ; both the pulp and the reagents enter the tank in a continuous stream and the discharge level is so regulated as to give the exact period ofFlotation Conditioning 911 Metallurgist
