Comments on the production information

  • AS OF 1988, PRODUCTS EQUAL 20,000 METRIC TONS PER YEAR OF 40 PERCENT CR2O3 FROM HANDSORTING AND 56,000 METRIC TONS PER YEAR AT 18 TO 22 PERCENT CR2O3 WHICH IS EXPORTED TO YUGOSLAVIA.
  • PRODUCTION BEGAN AT KAM DURING THE 1960S.

Comments on the reserve resource information

  • C.R.U. REPORTED THAT THE AVERAGE HEAD GRADE RANGES FROM 30 TO 40 PERCENT CR2O3. HOWEVER, LOWER GRADE ORES ARE ALSO MINED AT GRADES RANGING FROM 22 TO 28 PERCENT CR2O3. TWO TYPES OF ORE EXIST AT KAM, THEY ARE AN OLIVINE-RICH ORE AND A SERPENTINE ORE. B.G.R. REPORTS THAT THE OLIVINE-RICH ORE TYPICALLY GRADES 20.5 PERCENT CR2O3, 24 PERCENT SIO2, 33 PERCENT MGO, AND 10.3 PERCENT FE2O3; AND THE SERPENTINE ORE GRADES 23 PERCENT CR2O3, 21 PERCENT SIO2, 26 PERCENT MGO, 10 PERCENT FE2O3, AND 35.8 PERCENT AL2O3. B.G.R. ESTIMATED IN 1988 THAT RESERVES WERE BETWEEN 1.2 AND 1.5 MILLION METRIC TONS.
  • ALL INFORMATION BECAME AVAILABLE IN EARLY 1990 (AFTER THE NETWORK FLOW MODEL WAS BUILT). LOCATED IN THE TROPOJA DISTRICT. KAM IS 20 KM NW OF KALIMASH (SEQ. NO. 481-000-0010). COORDINATES ARE OF TOWN OF KAM. AS OF 1988, 4 MINES OPERATING: KAM-KEPENEK, ZOGAJ, LAJTHIZA, AND RRAGAZM (NEARLY EXHAUSTED), WITH TOTAL PRODUCTION OF 76,000 MTPY ROM. 1992 ADIT COMMENT: GRADE USED IS AN AVERAGE BETWEEN 20-41%. ROM CAPACITY AS OF 1992= 60,000 MT/YR; ROM PRODUCTION AS OF 1992 = 40,000 MT/ YR.

Comments on other economic factors

  • LOW GRADE ORE, AT 22% TO 28% CR2O3 (WITH A CR:FE RATIO OF 2.1:1) IS EXPORTED DIRECTLY TO A BENEFICIATION AT DEVA, YUGOSLAVIA. THE DEVA PLANT (LOCATED NEAR THE ALBANIAN BORDER) CAN TREAT HIGH OLIVINE ORES, MAKING IT THE BEST SUITED PLANT FOR LOW-GRADE KAM ORES. ORES GRADING 30% TO 40% CR2O3 ARE TRUCKED TO MJEDE FOR TRANS-SHIPMENT TO DURRES, BY TRAIN, FOR EXPORT. SOME SEPARATION OF WASTE AND ORE TAKES PLACE UNDERGROUND, HOWEVER, ALL WASTE IS TRANSPORTED TO THE SURFACE. COMPRESSED AIR DRIVEN LOADERS ARE USED UNDERGROUND. AS OF 1988, PRODUCTION WAS 76,000 MTPY RUN-OF-MINE ORE AT 25.3% CR2O3.
  • THE ORE DOES NOT UNDERGO ANY CONCENTRATION OR BENEFICIATION METHODS OTHER THAN SCREENING AND HANDSORTING.

Deposit TOTAL OPERATING DAYS PER YEAR WERE ASSUMED TO BE 250. KAM IS A STATE-RUN ENTERPRIZE, LOCATED IN THE TROPOJE DISTRICT, MINES THE CHROMITE OCCURRENCES OF THE TROPOJE ULTRABASIC MASSIF. THERE ARE FIVE MAIN DEPOSITS MINED IN THE TROPOJE MASSIF, EACH CONSIST OF TWO MAIN ORE-TYPES, OLIVINITES AND SERPENTINITES. THESE ORE TYPES ARE OUTLINED IN TABLE 6.3 IN THE MINING JOURNAL RESEARCH SERVICES REPORT ON MINING IN ALBANIA: AN EMERGING OPPORTUNITY, AND NOT IN TABLE 6.1 AS IS STIPULATED ON PAGE 59 OF THE REPORT. THE OLIVINITE ORES CONTAIN UNACCEPTABLY HIGH LEVELS OF SILICA. AT THESE LEVELS, 24%, THE SILICA GANGUE WOULD RESULT IN HIGH-VISCOSITY MELTS DURING FERROCHROME PRODUCTION. THIS PRODUCES VERY SLOW REACTION TIMES, WITH HIGH ENERGY CONSUMPTION, MAKING THE PROCESS UNECONOMIC. THE GREATEST POTENTIAL LIES IN IN THE SERPENTINITIC-ORES, WHICH CONTAIN MINIMAL SILICA, WITH HIGHER GRADES OF CHROMITE. RESERVES IN THIS DISTRICT ARE CONSERVATIVELY ESTIMATED AT 2 MILLION TONS. ANNUAL PRODUCTION FROM THE KAMIT MINE AVERAGES 65,000 TONS PER YEAR. THERE ARE SEVERAL OPTIONS OPEN TO INCREASE PRODUCTION TO 100,000 TONS PER YEAR. AT PRESENT, THE ORE FROM KAMIT IS SORTED, WITH MOST IMPURITIES REMOVED, BEFORE A PROPORTION IS EXPORTED TO YUGOSLAVIA. A PROCESSING FACILITY WITH A CAPACITY TO TREAT UP TO 100,000 TONS PER YEAR IS PLANNED TO BE CONSTRUCTED IN THE TROPOJE DISTRICT. THE TROPOJE MASSIF IS ONE OF THE BIGGEST CHROME-BEARING MASSIFS IN ALBANIA AND ITS POTENTIAL TO HOST ADDITIONAL DEPOSITS OF CHROMITE IS EXCELLENT.
