Smectite mineral grinding in Punjab

Mineralogy was determined by grinding each sample in a ball mill until the powder passed a 200 mesh screen. Random specimen mounts were made of the resulting powder and analyzed using a Siemens D-500 automated X-ray diffractometer. Mineral composition was determined by comparison of data with the JCPDS mineral data file, and is listed in Table 3

    The presence of clays in oil sands, especially swelling clays such as smectite, has an adverse effect on bitumen recovery and tailings management. Identification and quantification of clay minerals are therefore important to the oil sands industry. Two estuarine (E3 and E7) and two marine (M13 and M18) oil sands were used in this study

The smectite group consists of minerals with the 2:1 structure already discussed for mica and vermiculite, but with a still lower charge per formula weight, namely 0.6–0.2. As in vermiculite, the interlayer contains exchangeable cations (Figure 5).An idealized formula for a common soil smectite, the mineral beidellite
