High Specific Activity of Radium Isotopes in Baryte ... - MDPI

Radium-bearing barytes (radiobarytes) have been known since the beginning of the 20th century. They are mainly found as precipitates of low-temperature hydrothermal solutions. In anthropogenic environments, they frequently occur as crusts on oil industry equipment used for borehole extraction, in leachates from uranium mill tailings, and as a by-product of phosphoric …

Barite is ubiquitous and known to incorporate 226 Ra through the formation of a solid-solution. In U mining mill tailings, barite is one of the dominant sulfate-binding minerals. In such environments, sequential extractions are generally used to identify the U- and 226 Ra-binding phases and their associated reactivity.

The cyclone overflow reports to the sequential flotation circuit, which consists of bulk (silver-lead) flotation and regrinding, zinc flotation and regrinding, pyrite flotation, and barite flotation. The process produces four saleable concentrates, (bulk, zinc, pyrite and barite), that are subsequently thickened, filtered, and placed in sealed shipping containers for transport.

The grinding circuit consists of a SAG mill, ball mill and cyclones. The grinding circuit will be designed to reduce ore from an 80% passing size of 76mm to 40µm. The SAG mill will be a single pinion low aspect mill, operating in a closed circuit. The mill has an inside diameter of 3.8m and an effective grinding length (EGL) of 5.0m.

P&A and barite in general was conducted, and an experimental part was initiated. The potential financial savings are enormous if utilization of barite as a permanent barrier material is feasible. To potentially utilize settled barite as a permanent barrier material, a method to identify the settled barite behind the casing must be established.
