Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.

A process for the recovery of ammonia from an ammonia sulphate solution, the process comprising the method steps of: combining ammonium sulphate solution and quicklime (CaO) in a milling means to provide a reaction slurry; and running the milling means whereby the milling action of thereof acts to break up any gypsum precipitate as it forms in the reaction slurry or …

Steel can be produced via two main processes: either using an integrated blast furnace (BF)/basic oxygen furnace (BOF) or an electric arc furnace (EAF). While integrated players produce steel from iron ore and need coal as a reductant, EAF producers use steel scrap or direct reduced iron (DRI) as their main raw material.

A mixture of lime and sand taken in equal proportions in a mortar mill, mechanically prepared with water to make a paste of required consistency. The sand proportions in lime plaster control various properties such as shrinkage, strength, porosity, adhesiveness & fine sand is more suitable for making the plaster .

the mill plus the media has to be rotated, it requires many times more power than the conventional Detention or Paste slakers. 3. In applications where magnesium lime is to be used in place of calcium lime, slaking this type of lime is very difficult in regular slakers if pebble

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...
