Description: LIX 984NC Function/Use: THE PRODUCT IS USED FOR THE EXTRACTION OF MINERALS SUCH AS COPPER FROM THEIR ORES USING A SOLVENT EXTRACTION PROCESS. THEY ARE USED BY THE MINING INDUSTRY. WITH THE LIX® TECHNOLOGY THE COPPER CONTAINING ORE IS EXCAVATED AND CRUSHED AND PUT INTO HEAPS. DILUTE SULPHURIC ACID IS THEN PASSED THROUGH THE HEAP AND THE MINERALS WITHIN INCLUDING THE COPPER IS LEACHED OUT OF THE ORE. THE LEACHING ACID IS COLLECTED AND IS MIXED WITH A KEROSENE-BASED SOLUTION WHICH CONTAINS THE LIX® PRODUCT. THIS SOLUTION EXTRACTS THE COPPER FROM THE AQUEOUS SOLUTION AND THE AQUEOUS SOLUTION IS RECYCLED BACK TO START THE LEACHING PROCESS AGAIN. THE ORGANIC SOLUTION CONTAINING THE COPPER IS THEN CONTACTED WITH A STRONG SULPHURIC ACID SOLUTION WHICH DUE TO THE LOWER PH REMOVES THE COPPER FROM THE ORGANIC. THE ORGANIC IS THEN RECYCLED BACK TO START THE EXTRACTION PROCESS AGAIN. THE STRONG SULPHURIC ACID SOLUTION IS THEN SENT FOR HYDROLYSIS WHERE THE COPPER IS ELECTROPLATED OUT AS A PURE METAL. Characteristics: THIS PRODUCT IS AN AMBER COLOUR LIQUID WITH AN ODOUR OF PETROLEUM DISTILLATE.
