Bentonite is a sedimentary deposit; it is volcanic in origin and contains more than 50% montmorillonite. Bentonite is surface mined, dried, crushed, and sent through grinding mills to be sized based on customer requirements. Processed bentonite can also be chemically modified. Bentonite has a unique chemical structure that enables it to act as a sealant, binder, thickener, lubricant and absorption agent. Primarily, there are two types of natural bentonite: calcium and sodium.
Technavio’s analysts forecast the global bentonite market to grow at a CAGR of 2.09% during the period 2017-2021.

Commenting on the report, an analyst from Technavio’s team said: “Organically modified bentonite clay is used to improve the performance of clay for organic pollutants. Geosynthetic clay liners and geomembranes are widely used to control the migration of leachates from waste disposal facilities. Geomembranes possess many limitations and require well-constructed clay back up. Geosynthetic clay liners perform better and are easy to construct and reduce the volume of the lining system for disposal facilities. Geosynthetic clays have bentonite glued to geomembrane that helps in reducing permeability, improving their mechanical properties, and improving the retention capacity for various pollutants present in the leachates. However, bentonite has high retention capacity only with respect to inorganic ions. Thus, the clay needs to be organically modified to improve bentonite’s retention capacity for organic contaminants. The contents of organically modified bentonite and bentonite are chosen based on their geotechnical and sorption capacities.”
According to the report, technological advances in drilling technologies have revolutionized the oil and gas industry, and have enabled access to the most remote locations, unconventional formations, deep-water regions, and even the arctic. Such developments have played a key role in driving the consumption of bentonite for drilling. Horizontal drilling, coupled with hydraulic fracturing, has unlocked the unconventional potential of several regions such as the shale gas boom in North America and new discoveries in the offshore regions of Europe and Africa. In North America, horizontal drilling rigs constitute the largest share of the overall rig count, with 78%, whereas directional and vertical rigs account only for 11%, as of June 2015. Horizontal drilling allows the operator to drill long, lateral wells at sections of wellbores to access the entire reservoir. The growing adoption of lateral drilling techniques is estimated to boost the demand for bentonite, as it facilitates drilling of new reservoirs. These new drilling technologies also include hydraulic fracturing, which involves pumping water into underground reservoir rocks at high pressure to create fractures in the formation. This causes the trapped petroleum reserves, which can be extracted later, to be released. Hydraulic fracturing, when used in conjunction with horizontal drilling, provides drilling access to unconventional resources. This technique is widely used in new drilling activities, particularly in regions such as North America, APAC, Central and Latin America, and Africa, hence fueling the growth of the market.
Further, the report states that iron ore pelletizing from low-grade ores is a very important development in the beneficiation of iron ore. The quality of mined iron ore is decreasing globally. This has led to an increase in levels of silica in the concentrate. Bentonite is the most widely used inorganic binder in this industry. Bentonite improves the physical quality of pellet at all stages of agglomeration; however, it leads to high levels of silica. Bentonite assays have more than 50% SiO₂. Thus, in order to reduce or prevent the silica content while mining a lower grade ore, organic binders are preferred.
