The study sought to investigate how Tata Chemicals Company Soda ash mining activities have affected the indigenous Maasai community's livelihoods security.

Mining Process Pacific Soda uses the solution mining method to extract trona for soda ash production. Solution mining is a procedure that uses water and large wells to reach deep underground trona deposits. The pressure of the water pumps trona ore to the surface, where the brine solution (of trona and water) is processed into soda ash.

The first phase is energy transition. As part of our carbon neutrality plans, Solvay has set the goal to reduce greenhouse gas (GHG) emissions by 30% by 2030. To achieve this, we're replacing coal with cleaner energy resources across our soda ash sites. One way we're doing this is with biomass. At our Rheinberg site, for example, coal-fired ...

The method involves mining of sodium carbonate-rich water (referred as brine water), from Abijata Lake and transferring into the artificially made set of ponds for evaporation …

Soda ash is mined at Sowa using the borehole mining method. The salty water (brine) is pumped to the surface. On the surface, the water is put in large ponds. The solid material is then separated from the water by evaporation. The material is dried and taken to be processed into salt and soda ash.

Soda ash manufacturing. At Tata Chemicals Magadi's manufacturing facility, soda ash is obtained by washing and calcining trona, a naturally occurring form of sodium sesquicarbonate, extracted from Lake Magadi in Kenya. The alkali deposits at Lake Magadi exist as solid trona crystals with interstitial saturated alkaline liquor.
