Alteration

  • (Local) Low Grade Greenschist Metamorphism; Tropical Weathering

Analytical data

Result THE CLAYS LACK FINES AND HAVE POOR VISCOSITY WHICH RESTRICT USE TO EXTENDERS AND FILLERS. HOWEVER, CLAY HAS "EXCEPTIONAL" BRIGHTNESS (CRUDE ORE 75.9-92.6%) AND COULD BE PROCESSED TO A PAPER COATING GRADE PRODUCT. RUDIS ANALYSIS SHOWED <6% FE2O3 AND <2% TIO2. 80% OF THE MATERIAL HAS SIZE >2;

Host and associated rocks

  • Host or associated Host
    Rock type Volcanic Rock (Aphanitic)
    Stratigraphic age (youngest) Pleistocene

District name Ituni Bauxite Area

Comments on development

  • ECON.COM: FEASIBILITY STUDIES HAVE BEEN CONDUCTED BY ITC INC., NEW YORK (1981), AND BY MINING INDUSTRIAL ASSOCIATION (RUDIS), YUGOSLAVIA (1980). A PAPER COATING GRADE PRODUCT WOULD REQUIRE PROCESSING TECHNIQUES THAT INCLUDE MAGNETIC SEPARATORS, HYDROCYCLONES, AND CENTRIFUGAL CLASSIFICATION. IN 1989, PRODUCTION WAS PLANNED TO START SHORTLY AT A RATE OF 18,000 TPA OF KAOLIN.
