coarse barite ores and shaking tables for the concentration of fine barite ores are generally used. However, the very fine barite minerals (under 75 m) can not be concentrated efficiently using these gravity methods. For this reason, the flotation method comes to the fore in the efficient evaluation of very fine barite slimes.
Hence this research was aimed at investigating the effect of barite concentration on oil base drilling fluid density and rheology. Formulations and testing procedures were conducted in accordance with American Petroleum Institute (API) specifications. Experimental results showed that the increase of drilling mud is a direct function of increase ...
