Comments on the production information

  • IN 1982 TWO POTLINES WERE SHUTDOWN & BY JUNE 1983 THREE MORE POTLINES WERE SHUTDOWN DUE TO A DROUGHT THAT LEAD TO THE INABILITY OF THE HYDROELECTRIC STATION TO PROVIDE POWER. BY 1985 THE STATION STILL OPERATED W/ LIMITED ELECTRICITY BECAUSE THE RESERVOIR WAS STILL BELOW THE MINIMUM LEVEL IN ORDER TO OPERATE . 1980-1985 BROOK HUNT AND ASSOCIATES LTD. ALUMINUM PRODUCTION COST SURVEY, PG. 257. (RECORDS 1-4) 1988 BROOK HUNT AND ASSOCIATES LTD. ALUMINUM PRODUCTION COST SURVEY, PG. 1.133. (RECORDS 5-9) IN 1993, PLANT OPERATING AT 90% OF CAPACITY.
  • ALUMINUM SOLD TO CUBA UNDER BARTER ARRANGEMENT. (1990)

Comments on the reserve resource information

  • VOLTA ALUMINIUM CO. LTD. IS THE OPERATOR. SMELTER WAS OPERATING BELOW CAPACITY IN EARLY 1983. IT FINALY CLOSED COMPLETLY BY JUNE 1983 THROUGH 1984. THE LACK OF ELECTRIC POWER DUE TO INCREASING COSTS AND A PROLONGED DROUGHT WERE THE CAUSES. NEW POWER RATES WERE ESTABLISHED IN 1985 TO REOPEN THE SMELTER.

Comments on other economic factors

  • GOVT. TAKES 77% OF THE PROFITS; 46% AS STRAIGHT INCOME, A TAX FOR EDUCATION, AND A DIVIDEND TAX.
  • SMELTER USES BAUXITE IMPORTED FROM JAMAICA. (1988)

Deposit MILS DATA IN THE "INITIAL YEAR OF PRODUCTION" FIELD IS THE SMELTER YEAR OF START-UP. ALL DATA IS BASED ON THE 1987 ALUMINUM AVAILABILITY AND NET- WORK SUPPLY STUDY. ALL GRADE DATA IS IN TERMS OF WT PCT CONTAINED ALUMINUM. ALL SMELTER INPUT CAPACITY DATA IS IN MT OF ALUMINA CONCENTRATE. ALL SMELTER OUTPUT DATA IS IN MT OF ALUMINUM METAL PRODUCTION. TRANSPORTATION RECORDS 01 AND 02 ARE GENERAL DATA USED IN THE 1987 ALUMINUM AVAILABILITY STUDY. RECORDS O3 TO 06 ARE MORE SPECIFIC AND WERE USED IN THE NETWORK SUPPLY MODEL STUDY. PLANT HAS POWER DEMAND OF 315 MW, AND USES 15.43 KWH/KG AL. PLANT USES 60-65% OF THE AVAILABLE POWER FROM THE AKOSOMBO DAM.
