Limult Gypsum Mining and Processing Factory in Nigeria
Nigeria is known to have records of occurrences tin, columbite, tantalite, lead and zinc. In fact, mining in Nigeria he said to have started with mining of tin ore in 1905.
such mineral with great industry use and but largely underdeveloped in Nigeria, is gypsum. About one billion tones of gypsum deposits are spread over many sites in Nigeria. It is an important input for the production of cement. It is also used for the production of Plaster of Paris (P0P) and classroom chalk, etc.
Being a key input in cement production, a strategy for large scale mining gypsum is urgently required to sustain existing cement plants and meet future expansion.
The proccess of mining
The process starts by extracting gypsum rock deposits from the ground using a ‘JOY mine cutter’ that scores away at the face of the gypsum rock. This is then broken up and transported to the surface.
The rock is then crushed into smaller pieces and sent to the homogenizer, which allows for any variances in the gypsum size to be reduced, ensuring consistency in each bag of plaster. The rock from the homogenizer is ground down even further before it goes through what’s called the calcination process. Here, any water from the rock is removed in a low temperature kettle to create the first resemblance of plaster powder. This then travels through the mill, where the particle size of the powder is modified to suit the type of plaster being made.
At this stage, the plaster is almost ready! With the inclusion of a few additives that give each mix of plaster its own special properties, the plaster is pumped into bags and then palletised. Quality control checks are carried out across every batch to ensure that customers receive the same product, every time.
From here, the plaster leaves the Gypsum plant and is sent to merchants and distributors, ready for plasterers to buy. Once the plasterer mixes the product with water, it will return back into its original state, creating a plaster finish for their project.
