Nickel ore grinding energy determination
This study describes the application of an empirical method to estimate the energy consumption in laboratory of the primary grinding of nickel ore with a specific mineralogical texture. This method developed by Donda was previously used in iron ore from the Iron Quadrangle (Minas Gerais, Brasil) with the same purpose. Through the grinding test, performed under standard conditions and based on t...
متن کاملInvestigation of Leaching Kinetics of Smithsonite Ore
The leaching kinetics of smithsonite ore in acetic acid solutions, an environmental friend, and natural reagent was investigated. The influence of parameters such as reaction temperature, particle size, solid-liquid ratio and acid concentration was studied in order to reveal the leaching kinetics of smithsonite ore. In this study, experimental and statistical methods were carried out in order t...
متن کاملState and Ore Hardness Estimation in Semiautogenous Grinding ?
Semiautogenous milling is difficult to control both because of its non-linear behavior and the effects of overloading due to increases in the ore charge or variations in ore characteristics. Advanced control strategies and operational change detection methods are thus in need of strengthening using techniques such as state estimation. Non-linear state estimation is a complex task for which vari...
متن کاملKINETICS OF CARBOTHERMIC REDUCTION OF AN IRANIAN CELESTITE ORE
Two commercial methods are used for the production of strontium carbonate:1) Direct conversion of Celsetite to strontium carbonate by hot sodium carbonate,2) Carbothermic reduction of celestite with coal followed by water leaching of strontium sulfide(SrS) and its conversion to strontium carbonate.The present study has been made on the carbothermic reduction of celestite ores of Varamin (Iran) ...
متن کاملApplication of gravity separators for enrichment of South Chah-Palang tungsten ore
In the present study, the possibility of concentrating tungsten-copper vein ore in South Chah-Palang was examined using gravity separators including Jig Machine (-2360+600 μm), shaking table (-600+120 μm), and multi-gravity separator (MGS) (-120 μm). The representative sample contains 1.5% WO3 and 5.95% CuO. The main tungsten minerals were ferberite and wolframite and their appropriate liberati...
