    Ore Processing Challenges in Gold Operation Grinding

    Comminution 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. Over-grinding does not

    The grinding circuit of Concentrator I consists of two stages, the first operating in the open circuit mode. In literature, this configuration is known to be less energy efficient. At Samarco, it is common practice to apply the correction factor proposed by Rowland for open circuits before using the data from the first stage. However, even after the application of this factor, the specific

    Selection oof Comminution Circuits for Improved Efficiency

    Technically, grinding circuit efficiency refers to the amount of energy used to grind from a certain feed size to a product size as measured against a benchmark, such as that determined by Bond formulae adapted by Rowland (Rowland 1982). From a business perspective, efficiency may be measured according to the cost per unit of the grinding circuit product. That cost is comprised of the

The "infeed" mode is used for work with projecting heads that would prohibit "thru-feeding," the work is placed on the work-rest blade while one wheel is retracted and fed to an end stop. The wheel is then brought back, reducing the gap between the wheels, grinding the work. Surface grinding
