Production increases in Mexico in recent years corresponded with increased truck and rail shipments to key drilling areas in the Permian Basin. Most barite imports have been crude barite, which was processed at domestic grinding plants but, in 2019, an increasing proportion of barite from Mexico was reportedly ground barite shipped to
Although barite is usually used in powder form in the industry, it is seen that it is mainly used as aggregate in studies on concrete. There needs to be more research on its use in powder form.
