Deposit PROBLEM ARISING FROM PROCESSING ANATASE AS PRIMARY TITANIUM MINERAL IN PRESENCE OF IMPURITIES AS FE, CR AND PEROVSKITE. 30 M ORE CONTAINING ABOUT 19% BPL IS BENEFICIATED TO GIVE A 79% BPL CONCENTRATE. THIS RECORD CONTAINS DATA FROM DUPLICATE RECORD ISM0392 WHICH HAS BEEN DELETED FROM MAIN MRDS.
Deposit THIS RECORD CONTAINS DATA FROM DUPLICATE RECORD ISM0392 WHICH HAS BEEN DELETED FROM MAIN MRDS.
Deposit ABOVE THE PRIMARY MAGMATIC ROCKS 4 ALTERATION ZONES HAVE BEEN DISTINGUISHED (TOP TO BOTTOM): LATERITE ZONE, ANATASE ZONE, MIXED ZONE, AND APATITE ZONE. FOR PHOSPHATE MINING, MIXED ZONE AND APATITE ZONE ARE OF PRIMARY INTEREST. UPPER ORE ZONES: APATITE, SECONDARY PHOSPHATES (CRANDALLITE, GORCEIXITE, WAVELLITE), ANATASE, LIMONITE, MICA, MAGNETITE, ARGILLACEOUS MATTER. LOWER ORE ZONES: APATITE, ANATASE, PEROWSKITE, DIOPSIDE, MAGNETITE, VERMICULITE, PHLOGOPITE, BIOTITE, QUARTZ, AMORPHOUS SILICA.
