ESTAGEO LLC TEPLOENERGETIK LLC Innovative innovation reusing phosphogypsum T. Bashlikova, E.V. Adamov, M. Gusakov

Slide 2

Apatite think Apatit JSC Phosphogypsum is result of preparing apatito-nepheline metal . Extensive apatite stores are notable and are mined in the accompanying nations : Brazil (2,0 billion tones ), South Africa (1,0 billion tones ) и Finland (1,5 billion tones ). Add up to world stores of apatite metal is 23,3 billion tones .

Slide 3

Phosphogypsum Dumps when all is said in done, Russia has officially amassed around 200 million tons phosphogypsum (yearly making of the material in RF is roughly 10–11 million tons).

Slide 4

The desperation of the critical thinking biological issues Development of uncommon earth components from dumps Increase sought after and cost of uncommon - earth components on the planet Depletion of normal assets of gypsum and monetary attainability of receipt from phosphogypsum dumps

Slide 5

Global utilization of uncommon earth components in 2010

Slide 6

Consumption of uncommon earth components

Slide 7

The requirement for hunt of the new reusing innovation of phosphogypsum In European nations settle impose for the phosphogypsum dumps is equivalent 30 euro for every ton In Russia settle charge for the phosphogypsum dumps is equivalent 8 USD for each ton Waste of 2-4-th class of risk Waste of 4-th class of threat

Slide 8

Well-known procedures reusing phosphogypsum Well-known procedures reusing phosphogypsum and extraction of REM are work escalated and require sufficiently huge cost of capital development and sorting out of extra creation, and now and again rather ecologically perilous.

Slide 9

Bioleaching Technology Leaching operator in the innovation is a particular relationship of microorganisms.

Slide 10

Bioleaching Technology Biocoenosis Phosphogypsum Strain - 1 Strain - 2 Selective relationship of microorganisms … ... Strain-n

Slide 11

Research Data Bioleaching innovation result to : Rare-earth metals are extricated in this procedure into arrangement (REM is 55–70% [this study] and can be expanded to 85–90% with strengthening process ) The bioleaching release of sulphuric corrosive is 5.5 circumstances lower than release in sulphuric - corrosive hydrometallurgical prepare At the finish of this procedure on the fate of hydrometallurgical handling is the cleared material with no phosphoric and fluoric aggravates An improvement, increase and less costly technique for phosphogypsum preparing, more great environmental conditions

Slide 12

Economic Impact down the middle Russian stores phosphogypsum the uncommon earth metals just are gauge at 55 billion USD!
