Optimization of Flotation Process for Reduction of Alumina and Silica from Screw Classifier Overflow of an Iron Ore Washing Plant
Reverse flotation process was optimized by an experimental programme based on statistical analysis for reduction of silica and alumina levels from screw classifier overflow so as to enrich iron values. Flotation of alumina and silica bearing minerals with Sokem 521C and starch as collector and depressant respectively was studied to estimate their optimum levels at different particle sizes. A tw...
متن کاملenvironmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Modeling and Simulation of Processes from an Iron Ore Sintering Plant
This work presents the mathematic models of the basic processes from an iron ore processing plant. Based on the mathematic models, using the Matlab/Simulink platform, it was achieved the simulation of the dosing process and simulation of the sintering process. The achieved mathematic model allows the determination of the material flows in the charge at their chemical composition variation, or a...
متن کاملIncreasing efficiency of thickener operation in concentrate plant of iron ore mine using coagulation-flocculation
Thickener is a main and fundamental step in modern mining separation processes. In this research, the effectof flocculant consumption rate and feed solid concentration of settling rate of layers was studied with differentconcentrations in iron ore mine of Jalalabad, Zarand, Kerman, Iran. The experiments were performed in two1000 ml graduated cylinders (61 and 62 mm diagonal an...
متن کاملExpansion and Modernization of an Iron Ore Pelletizing Plant in Northern Sweden
The paper describes the main drive systems of an iron ore pelletizing plant and related important design aspects. It is shown how today’s drive systems provide the desired flexibility for the process and lead to high energy efficiency and system reliability. With respect to electric drives expansion projects have many technical issues in common with green-field installations. However, there are...
