Disposal of spent drilling fluid at uranium deposits using flocculants is a process of cleaning and neutralizing spent drilling fluid in order to minimize its negative impact on the environment. The development of a plant for the disposal of spent drilling fluid in uranium deposits using flocculants is an important task, since the spent drilling fluid contains various contaminants, including heavy metals and radioactive elements, which can harm the environment. The use of flocculants in this process improves disposal efficiency, as they are able to remove solids and other contaminants from the drilling fluid, which reduces its toxicity and reduces the amount of waste released to the surface. The development of a plant for the disposal of used drilling fluid should include several stages, such as the selection of suitable flocculants and determining their optimal dosage, the development of a dewatering and solid waste recovery process, and the selection of appropriate equipment and technologies for the process. In addition, the design of the plant must take into account compliance with local regulations and environmental regulations, as well as ensure the maximum efficiency and economy of the process. The result of the study is the creation of a useful model for the disposal of waste drilling fluids, which relates to the field of disposal of waste drilling fluid accumulated during the construction of technological wells for underground leaching of uranium ore.
