During the drilling of oil and gas wells, barite is often used as a weighting agent to increase the specific gravity of drilling fluid mud, thereby preventing the drilling fluid mud from spouting and ensuring the safety of underground operations (Al Hamad 2020; Mahmoud 2018; Zhang 2017). When barite is added to drilling fluid mud, its particle size is required to be no less than 325 meshes to prevent its precipitation in the wellbore (Bageri 2017; Risthaus 2001). At the same time, the specific gravity of barite should be greater than 4.2, and the mass fraction of BaSO4 should not be less than 95%. In the process of oil production, due to the change in temperature and pressure, the thermodynamics of the aqueous solution is unstable, and under the action of chemical incompatibility, it is easy to cause scaling to block the pipeline and formation when the time is too long (Geri 2017). Compared with the carbonate scale, the barium sulfate scale caused by barite is extremely difficult to remove, and there is no effective method (Mahmoud 2018; M. U et al. 2000). Therefore, due to its stable chemical properties, low complexation constant, and low solubility product, the prevention, and removal of barium sulfate scale has always been an international problem.

Table 14.3 represents the variation of the plastic viscosity of mud with temperature at different concentrations of bentonite. With an increase in temperature the plastic viscosity decreased but with an increase in the concentration of bentonite, plastic viscosity increased. The optimum concentration of bentonite was determined to be 3% (30 g), 3.5% (35 g) and 4% (40 g), because higher concentrations of bentonite may cause damage to the formation and a lower concentration of bentonite will not give accurate results. Different concentrations of barite were mixed with predetermined concentrations of bentonite and the variations in the drilling fluid properties were recorded. Table 14.4 shows the variation of drilling fluid properties in bentonite+barite mud. The variation of plastic viscosity with temperature at different concentrations of barite in predetermined concentrations of bentonite is shown in Table 14.5. The plastic viscosity of the drilling mud decreased with an increase in temperature. Barite is used in the petroleum industry as weighting material in the formulation of base mud. It also increases the hydrostatic pressure of the drilling mud, allowing it to compensate for higher-pressure zones. Therefore, viscosity plays an important role in the formulation of drilling mud, and the optimum concentration of barite in drilling mud was chosen according to the plastic viscosity and density. The concentrations of barite which were determined to be optimum are 4% (40 g) in 3% (30 g) of bentonite, 1% (10 g) in 3.5% (35 g) of bentonite and 2% (20 g) in 4% (40 g) of bentonite.

In Canada, barite was first extracted in 1866 from a mine at Bass River, Nova Scotia. Barite is found in almost every province; however, economically significant deposits are restricted to Newfoundland, Nova Scotia, Ontario, and British Columbia. Between 1940 and 1978, almost all of the barite mined came from one of the largest operations in the country: the Magnet Cove Barium Corporation, near Walton, Nova Scotia. Mining initially took place at the surface, but later was moved underground. Although the mine and quarry are now flooded, the mill at Walton still operates.

Besides the oil and gas resources, Nigeria is also endowed with solid minerals (Adekoya, Kehinde-Phillips, and Odukoya 2011). These minerals include gold, coal, bitumen, talc, gypsum, iron ore, rock salt, kaolin, gemstone (NHC 2020), limestone, tin ore, columbite and zinc/lead sulphates (Alison-Madueke 2009) and a host of others (see Figure 4). Not less than 75% of solid minerals are of great relevance in the industry by the Nigerian Geological Survey Association. Solid minerals are divided into the following; energy minerals (coal, lignite, atomic minerals), major industrial metals (base metals, ferrous metals), specialist metals (tin, wolfram, tantalum), precious metals (gold, silver, platinum), gemstones (precious and semi-precious), and Industrial minerals and construction materials. Over 3 billion metric tonnes deposits of iron ore were estimated to be in Enugu, Kogi, Niger, Lagos, and Federal Capital Territory. The deposits of talc in Osun, Niger, Ogun, Kaduna and Kogi States are over 40 million tonnes. Located in Taraba and Bauchi States barite which is over 7.5 million tonnes (Jack, Nkwocha, and Odubo 2016).

Barite (BaSO4) as an important industrial mineral has various applications based on its physical and chemical properties. Physical properties of barite are mainly related to its high specific gravity, and chemical properties linked to its low solubility. Barite is the only source of barium and is used as a weighting agent, extender, filler in the printing paper industry, paints, oil well drilling mud, and so on. In general, the application of barite depends on the purity and its industrial market is divided based on different production grades: drilling mud, filler, and chemical grade. On the other hand, particle size distributions, specific gravity, and percentage of impurity content are the main factors for barite production specifications. Barite ores are typically associated with silicate, carbonate, iron oxide, sulfide, and clay minerals (Ciccu et al. 1987; Harris 1988; Kecir and Kecir 2015; Raju et al. 2016).
Prediction of barite recovery and grade by multiple linear regression (MLR) analysis in concentrating of barite tailings by using multi-gravity separator (MGS)

Barite (BaSO4) is one of the most important minerals among industrial minerals. The main uses of barite mineral are as a weighting agent in drilling mud, as fillers in the paint, glass and paper sectors, in the production of different barium compounds, and also used for medical (pharmaceutical) applications due to its adsorption properties of X-rays and gamma rays.
