Comments on the production information

  • A SEPARATE LEACHING CIRCUIT TREATS ZINC OXIDE FUME FROM THE LEAD SMELTER. PURIFICATION OF THE SOLUTION BY FILTRATION PRODUCES A HIGH CADMIUM RESIDUE WHICH IS THE PRIMARY FEED TO THE CADMIUM PLANT. THE FILTRATE IS THEN SENT TO THE ELECTROLYTIC PLANT FOR RECOVERY OF THE ZINC. FOUR ACTUAL ZINC PRODUCTS ARE PRODUCED: PRIME WESTERN ZINC (19,000 MT/YR), HIGH GRADE ZINC (100,700 MT/YR), SPECIAL HIGH GRADE ZINC (76,200), AND ZINC ALLOYS (76,100).
  • ZN PRODUCTION ROSE BY 8.4% TO 139,600 MT FOR 1996.
  • GRADE GIVEN FOR ZINC IS FOR THE HIGH GRADE ZINC, WHICH ACCOUNTS FOR THE LARGEST AMOUNT OF PRODUCTION. THE OTHER GRADES ARE AS FOLLOWS: PRIME WESTERN ZINC: 99.2% ZN; SPECIAL HIGH GRADE ZINC: 99.997% ZN; ZINC ALLOYS: VARIES BY CUSTOMER. GRADE GIVEN FOR PRODUCT D IS FOR SULFURIC ACID.

Comments on other economic factors

  • ABOUT 75% OF THE CONCENTRATE IS PROCESSED THROUGH THE CONVENTIONAL LEACHING CIRCUIT. THE OTHER 25% IS PROCESSED THROUGH A PRESSURE LEACHING CIRCUIT; THIS IS WHERE THE ELEMENTAL SULFUR IS PRODUCED, WITH THE REMAINING SOLUTION RETURNING TO THE CONVENTIONAL LEACHING CIRCUIT.
