Develops a new type of crushing machine for mining/comminution Saves large amounts of energy in mining Sustainable mining
Get PriceComminution is the reduction of solid materials from one average particle size to a smaller average particle size by crushing grinding cutting vibrating or other processes [1] [2] In geology it occurs naturally during faulting in the upper part of the Earth s crust [3]
Get PriceIt starts with blasting followed by crushing and the grinding or milling of the mined rock Mining is an energy intensive industry that uses around 7 percent of world s generated energy Of this almost half goes to comminution Innovation is needed to reduce energy consumption from the currently inefficient comminution process
Get PriceIt focuses on the dilemma of needing to grind materials to ever finer sizes while maintaining reasonable energy costs The selection and sizing of stirred mills for regrinding and ultrafine
Get PriceMines rarely have control over the cost of energy so it is vital that comminution processes meet process objectives while consuming as little energy as possible Energy efficiency is one of the pillars of comminution circuit design Ignoring this can be the difference between a profitable operation and a money loser

Get PriceThis selectively liberates the valuable minerals from the waste The waste is then removed from the comminution circuit so that only the valuable mineral ore remains in the circuit for processing By effectively removing the waste material and creating microfractures in the valuable ore we can achieve energy savings of up to 70%
Get PriceThere is a great deal of activity directed toward improving ore characterization to predict AG/SAG mill energy requirements as well as developing improved models and instrumentation for optimization and control of comminution circuits Instrumentation modeling and control functions in particular have benefited from rapidly advancing computer technology
Get PriceComminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes When the target grind is not achieved under grinding it results in a higher number of unliberated gold particles This in turn causes a loss in gold recovery and therefore revenue
Get PriceComminution is the action of reducing a material especially a mineral ore to minute particles It is an essential process for much of the mining industry where it is used to fracture rock ores into fine particles in order to liberate and then recover the valuable minerals e g copper gold platinum zinc magnetite
Get PriceIn all of the mining milling smelting and refining processes comminution is by far the largest energy consumer It is estimated to consume 3% of all electric power generated in the world which translates into high costs and greenhouse gas production — Natural Resources Canda How it works
