The most important problem in boric acid production from colemanite ores with H2SO4 is the formation of MgSO4 impurity due to the partial decomposition of clay minerals in the reaction media. Increase of MgSO4 concentration in solution may be balance

Potassium pentaborate octahydrate (K 2 B 10 O 16 ·8H 2 O) is used as an additive in industrial and automotive lubricants. While using in high-pressure lubricants, the particle size of crystals may be very important to obtain a stable dispersion. The

This study is based on the hypothesis claiming that solubility and crystal growth and dissolution kinetics of K 2 SO 4 are dominated by the surface potential distribution. Specific anion adsorption is the main reason for the occurrence of negatively

In this study the shear strength of filter cakes of various minerals such as dolomite, calcite, quartz and kaolin was investigated. Shear strength of the mineral filter cakes are influenced by the particle size and shape and surface tension as well a
