| Abstract: | This paper deals wlth the surface chemistry, colloid chemistry and electrochemistry of the rectorite-sodium carbonate (Na_2CO_3)-water (H_2O) system. The mechanism of formation of the most stable gelatinous structure has been explained in terms of the crystallochemical characteristics and electrokinetic properties of rectorlte. Our studies show that rectorite is an excellent drilling mud material, much better than bentonite with respect to its colloidal prope rties. A great wealth of data obtained from pulpification test, chemical analysis, X-ray diffraction and electron microscopic examination provide evidence suggesting that the major factors affecting the rate of rectorite pulpification involve the content, crystallinity, grain-size, form and pH of reetorite and its associated minerals. |
