NEW METHODOLOGY TO IMPROVE PRODUCTIVITY OF ,, improve overall process, energy and water efficiency Implementation of the PIO methodology has delivered significant improvements in mine efficiency, mill throughput and reduced operating costs at mines around the world (Dance et al, 2006) For example, increases in mill throughput of 5 to 20 percent have been measured at some sitIsaMill, This results in the generation of fine particles at greater energy efficiency than tumbling mills For example, grinding a pyrite concentrate so that 80% of the particles are less than 12 µm (0012 mm) consumes over 120 kilowatt-hours per tonne (kWh/t) of ore in a ball mill using 9 mm balls, but only 40 kWh/t in an IsaMill using a 2 mm ,Optimization of mill performance by using, influences the grinding efficiency In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind Optimization of mill performance by using online ball and pulp measurements J o u r n a l P a p e rConventional Uranium Mills | NRCgov, Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached) In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore (In addition to extracting 90 to 95 percent of the uranium from the ore, the leaching agent also ,Mineral processing | metallurgy | Britannica, Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
