The Kenticha tantalite ore have higher concentrations of Li and U and other oxides of alkaline, transition and rare earth elements (REE).Thus, the beneficiation of this ore needs new design for better enrichment and the production of high quality oxides and metallic forms of Nb and Ta. 19 Following the beneficiation of the ore, a number of processes may be required based on the
Processing extraction and refining. The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes the tantalum and niobium values to ...

Provides an orthodox statistical approach that helps in the understanding of the designing of unit processes.
Sep 19, 2018 The tantalum minerals, tapiolite, and microlite were widely dispersed in grain sizes of 50 to 100 microns. No beryl was observed, and the niobium assay was less than 0.002% Nb2O5. Fine-grained mica, accounting for only a small percentage of the overall sample, was dispersed typically in the 100 to 200 micron range.
Located two kilometres north of the town of Ravensthorpe in Western Australia, Galaxy is mining pegmatite ore and processing on site to produce a spodumene concentrate and a tantalum by-product. In 2016 Galaxy engaged a team to upgrade and modify the existing circuit to improve product recoveries and increase the annual production of the plant.

Jun 30, 2020 Special Issue Information. Mineral liberation is essential for designing an optimal mineral processing. It depends on the mineralogical and textural characteristics of ores. The estimation of the liberation degree is fundamental to estimate the efficiency that can be achieved using a separation process.
Tantalum mineral concentrates may contain from two to more than five different tantalum-bearing minerals from the same mining area.The sale of tantalum mineral concentrates is based on a certified analysis for the tantalum oxide (Ta 2 O 5) they contain,with a typical range from 20% to 60% depending on the mine source.
Sep 20, 2021 Tantalite contains tantalum, see comments for rossovskyite. These minerals form 83 percent of the minerals tabulated. Only 59 percent contain tantalum. One thing that is favorable is all the minerals are oxides, there is not a mix of oxides and sulfides which would complicate metallurgical plant design and recoveries.
