In Uganda, Lake Katwe is the major source of brine containing valuable minerals (Kirabira et al. 2013). The reserve contains about 22.5 million t of crystalline salts (Morton 1973; UDC 1997). At the deposit, salt mining has been taking place since precolonial times (Barrett-Gaines 2004) using rudimentary methods.

Salt is obtained from two sources: rock salt and brine. Rock salt is simply crystallized salt, also known as halite. It is the result of the evaporation of ancient oceans millions of years ago. Large deposits of rock salt are found in Nigeria. Brine is water containing a high concentration of salt.Web

Salt can be mined from rock salt either by traditional mining practices using heavy equipment underground, or by pumping hot water in pipes into the salt deposit, where the hot water dissolves the halite. The resulting salt water is then pumped to surface and evaporated to yield salt. This is called"solution mining". In some modern dry salt ...Web

Between the onset of mining in 1962 and the end of 1989, 21 mining induced seismic events with magnitudes of 2.3 to 3.6 were recorded. Horner (9) attributes these events to "brittle failure orWeb

The laboratory isothermal extraction experiments indicate that various types of economic salts such as thenardite, anhydrite, mirabilite, burkeite, hanksite, gypsum, trona, halite, nahcolite, soda ash, and thermonatrite exist in the brine of Lake Katwe. In addition, the salts were found to crystallize in the following the sequence: sulfates ...Web

The unit production cost of halite was 0.2629 and 0.4724 $/kg with an NPV of $2,447,853 and -12,085,796 of the solar salt and mechanical evaporation processes respectively. As a result, the solar salt extraction process proved feasible from both engineering and economic standpoints and thus can be scaled up to a pilot-scale using conventional ...Web

Caverns can be made artificially in rock salt by salt solution mining, which involves dissolving salt with water and pumping the brine back up to the surface (Figure 11). For caverns in halite, one cubic meter of rock can be dissolved with seven to eight cubic meters of fresh water pumped into the cavern.Web

Here, we present uniaxial and confined triaxial compressive test data for bedded salt rock specimens. We use the term "salt rock" to refer to any lithotype found in a salt rock sequence, whereas we use the term "halite" or, sometimes, "rock salt" to specifically refer, in this article, to a bed or specimen of halite (NaCl). 2.Web
