Comments on development

  • NON-GEOLOGIC CONSTRAINTS ON DEVELOPMENT OR EXPANSION IN 1-5 YRS. (). DEVELOPMENT(YES); EXPLORATION(UNKNOWN); AN UNDERGROUND OPERATION HAS BEEN DEVELOPED IN 1975. AVERAGE U3O8 CONTENT OF PHOSPHATES IS 95 PPM. ROM ORE MAY SOMETIMES GRADE UP TO 75 % BPL; AT PRESENT 5 ORE BODIES ARE WORKED THROUGH 6 OPERATIONS. THREE TYPES OF CONCENTRATES ARE PRODUCED 70/72 GRADE, 73/75 GRADE AND 75/76 GRADE. ACCORDING TO WORKABILITY AND MINERALOGY 6 TYPES OF ORE HAVE BEEN DISTINGUISHED: MATRIX FREE ORE (RICH ORE); CALCAREOUS ORE; SILICEOUS PHOSPHATE (HARD ORES); MIXED CALCAREOUS-SILICEOUS ORES (WITH 50 % APATITE); MARLY PHOSPHATE (50 % APATITE, SOFT FRIABLE ROCK); ARGILLACEOUS PHOSPHATE (LOW GRADE ORE RICH IN CLAY). CHEMISTRY: 1) CONCENTRATE SCREENED WASHED: 70/72 % BPL, 32.46 % P2O5, 49.9 % CAO, 3.7 % F, 0.41 % CL, 3.8 % CO2, 0.88 % AL2O3 + FE2O3, 0.34 % OM, 5.75 % LOI, 5.13 % SANDY MATTER; 2) CONCENTRATE WASHED AND SCREENED: 73/75 % BPL, 33.9 % P2O5, 52.3 % CAO, 3.86 % F, 0.04 % CL, 4.0 % CO2, 0.47 %
  • AL2O3 + FE2O3, 0.3 % OM, 6.06 % LOI, 2.62 % SANDY MATTER; 3) CONCENTRATE WASHED AND CYCLONED: 75/76 % BPL, 34.6 % P2O5, 52.7 % CAO, 3.96 % F, 0.04 % CL, 3.6 % CO2, 0.47 % AL2O3 + FE2O3, 0.27 % OM, 5.62 % LOI, 2.00 % SANDY MATTER.

Deposit THIS RECORD WAS COMPILED FOR THE INTERNATIONAL STRATEGIC MINERALS INVENTORY. THE DATA WERE USED IN PREPARATION OF THE USGS CIRCULAR 930 SERIES OF REPORTS. MINERAL RESOURCE CATEGORIES AND CODES HEREIN ARE FROM THE INTERNATIONAL CLASSIFICATION SYSTEM RECOMMENDED BY THE UNITED NATIONS GROUP OF EXPERTS ON DEFINITIONS AND TERMINOLOGY FOR MINERAL RESOURCES. (SEE NATIONAL RESOURCES FORUM, V. 4, NO. 3, P. 307-313.). SURFACE, UNDERGROUND 1 M SCREENING YIELDS 70/72 % BPL PRODUCTS; WASHING & CYCLONING RAISES BPL TO 73/75 % DEFINITIONS OF TERMS AND LIMITS OF ORE BODIES AS USED IN EVALUATION OF RESERVES IN JORDAN: "ORE" CONTAINS MORE THAN 27.5 % P2O5, I.E. 60 % BPL; "PROTORE" CONTAINS 23-27.5 % P2O5, I.E. 50.3-60 % BPL; "SUB-PROTORE" CONTAINS 15-23 % P2O5, I.E. 33-50 % BPL; ONLY PHOSPHATE BEDS THICKER THAN 1 M ARE INCLUDED IN RESERVE CALCULATIONS. IT IS ASSUMED THAT 1 M3 DRY ORE IS EQUIVALENT TO 2 TONNES. ADDITIONAL NEWS: PROVEN RESERVES ARE STATED AT MORE THAN 300 MILLION TONNES (PHOSPHORUS &
Deposit POTASSIUM, MAR/APR. 1982, P.15, LONDON). SHEDIYAH DEPOSIT CONTAINS HIGH GRADE ROCK WITH 75-80 % BPL (MINING ANNUAL REVIEW, 1982, P.479, LONDON)
Deposit CRYSTALLINE BARITE VEINS OF VARIABLE THICKNESS. THE VEINS ARE VERY LONG.
