Title:
FULL-PARTICLE FRACTION SORTING AND PRE-ENRICHMENT PROCESS FOR COAL-BASED CO-ASSOCIATED MINERAL GERMANIUM
Document Type and Number:
WIPO Patent Application WO/2023/216691
Kind Code:
A1
Abstract:
Provided is a full-particle fraction sorting and pre-enrichment process for coal-based co-associated mineral germanium, the process comprising the steps of: S1: feeding and grading preparation; S2: X-ray sorting, which involving: feeding the oversize materials into an X-ray efficient sorting unit (2) for sorting; S3: micro-bubble flotation, which involving: feeding the undersize materials into a micro-bubble flotation unit for sorting, which involving: S3.1: passing the undersize materials through a crusher (7) and an ore grinding machine (8) in sequence to achieve sufficient dissociation; S3.2: grading the ore-ground product by means of a hydraulic grading cyclone (9), feeding the overflow product into the micro-bubble flotation and separation unit for sorting, and returning the underflow product to the ore grinding machine (8) for re-grinding; S3.3: feeding the overflow product of the hydraulic grading cyclone (9) and a reagent into a forced stirring mineralization device (12) for stirring and mineralization; S3.4: roughing the stirred and mineralized mixture by means of a flotation machine (13); and S3.5: selecting the overflow product from the flotation machine (13) by means of a flotation column (16), such that the coal-based co-associated mineral germanium can be efficiently sorted.
