Type of structure Regional
Structure description Folded Metasedimentary Rocks Of Precambrian To Paleozoic Age.

Comments on the geologic information

  • PRINCIPAL MINERAL ASSEMBLAGES: SCLT + WLFM + BSMN + QRTZ + DPSD + GRNT + EPDT + HBLD + SRCT + CLCT + FLRT + APTT. MOST OF THE ORE COMES FROM THE "MAIN VEIN", WHICH MEASURES 1,500 M ALONG STRIKE, 1,500 M DOWN DIP AND 3.5 TO 5 M THICK. ORIGIN OF THE DEPOSIT IS CONTROVERSIAL - SOME WORKERS REGARD IT AS A METAMORPHOSED STRATABOUND DEPOSIT.

Comments on the reserve resource information

  • PRODUCTION CAPACITY: 600,000 METRIC TONNES/YEAR (ANSTETT ET AL, 1985). IN 1984, TREATED 2,350 MT/D OF ORE GRADING 0.52% WO3 (STAFF, 1959).

Comments on development

  • SYNTHETIC SCHEELITE PLANT COMMISSIONED IN MAY, 1959 (STAFF, 1959). IN 1979, THE SANGDONG PLANT WAS REPORTED TO PRODUCE THREE PRODUCTS: A NATURAL SCHEELITE WITH 72% WO3, AN ARTIFICIAL SCHEELITE AT 74% WO3 AND APT AT 89% WO3 - IN THE FOLLOWING PERCENTAGES 22.3%, 16.5% AND 61.2%. TOTAL PRODUCTION WAS 3000 TONNES/YEAR CONTAINED WO3 (SMITH, A., 1979, P. 60).
