Tantalite valley old report , previous drilling ,showing high grade lithium, with a test done a sample containing tantalum,niobium. ,lithium , beryllium, bismuth, quote , The gravity separation tests were conducted on fractions below 0,5 mm, and between 0,5 and 7,5 mm in size. The former contained 12,4 kg/t (1,24 % of Ta2<>5 - ND2O5). The tests showed the possibility of recovering high-grade concentrate (65 % Ta20s - ND2O5) from the jig concentrate by grinding and table concentrations. Grinding was done to approximately 30 mesh. Although the larger sized fraction contains only 1,9 kg/t (0,19% Ta20s - Nb20s), it can be fairly readily concentrated to obtain the concentrate containing 60 % (Ta20s - ND2O5). In the first case at least 65 %, and in the second, 80 % of the mixed oxides were recovered.
Heavy-medium separation was found to be an efficient method for the recovery of spodumene and amblygonite, provided that the content of thin mica flakes in the material does not exceed 1,0%. The presence of greater quantities of mica flakes results in high losses and medium, to lower grades of concentrate, and low recovery.
Mixed tantalite and columbite constituted between 0,19 and 1,24 % of the heavy-medium separation (HMS) concentrates, and more than 8 0 % of the tantalite-columbite may be recovered by crushing and gravity concentration.
Spodumene concentrates having a L1O2 content of approximately 5 % can be produced in a single stage and concentration, but retreatment is necessary for the production of a significantly higher grade.
Estimates obtained from similar deposits in Namaqualand indicate that only around 2 0 % of the spodumene and 15 % of the beryl, tantalite-columbite, and mica in the ore are recovered by present-day methods of hand sorting. The waste-dumps therefore contain considerable quantities of these minerals.
Unfortunately, no promising method for the recovery of beryl has, however, yet been found.
Bismuth as value of approx 11000 Us$ currently in China . https://price.metal.com/prices/bismuth-selenium-tellurium
Beryllium I mentioned in previous post , which I was amazed of value , two ores containing beryllium in bible ,
While mining tantalum and achieving high grades , byproducts will be very beneficial to revenue ,
Larry as found a top consumer of the tantalum, no middle man , producing high grade concentrate , in talks with another potential customer,audit done , so that means there is something to sell , hours increased to achieve more production , and added to team with Mr Odilon Ilunga who in my eyes will be very beneficial to co ,
