The Bond work index determination according to the standard Bond's test is done on all these samples with compara-tive sieve size of 74, 105 and 150 microns. The Bond Work Index is calculated using the formula (Bond, 1961): (√ √) (1) where: W i – Bond work index (kWh/t); P c

MoreThe water hardness is expressed by an index, or total hardness, TH, in degrees, each degree determined by the following formula: 1 degree (°F : French unit) = 4 mg/liter of calcium or 2.43 mg/liter of magnesium or 10 mg of limestone. The waters are classified according to their TH (French TH) 0
