Industrial Grinding Estimation of Blended Ore fromIndustrial Grinding Estimation of Blended Ore from Porphyry Copper Deposit Irena Grigorova1, Marin Ranchev2, Teodora Yankova3, Ivan Nishkov4* 1Associate Professor DSc, University of Mining and Geology "St. Ivan Rilski", Department of Mineral Processing and Recycling, Sofia, Bulgaria.. Modeling of Vibration Condition in Flat Surface Grinding ProcessThe experiments of the flat surface grinding process were carried out to study grinding forces variation and process vibration conditions to validate the results of the vibration model. The results show that the change of depth of cut and the cutting speed induces a nonlinear dynamic behavior of the process, and the normal component makes a greater contribution than the tangential component in. Uranium Mining and Extraction from OrePrior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding. The roasting process is meant to burn carbonaceous species trapped within the ore and make the ore more reactive to the leaching treatments. In some cases, the ore is roasted with salts in order to improve solubility of contaminant metals, such as vanadium, in the leach solution
