Microwave Vacuum Carbothermic Reduction and Sulphidation of a Low Grade Nickeliferous Silicate Laterite Ore
The international resources of nickel sulphides are quickly diminishing. In order to satisfy forthcoming nickel demands, the feasible mining of nickel laterite deposits is imperative. Nickel laterites cannot be easily treated since the nickel is finely disseminated throughout the ore. Therefore, …

Water Quality Impact on Flotation Response: A Focus on Specific Ions and Temperature
… the chosen parameters. A low-grade copper-nickel platinum group element (Cu-Ni-PGE) ore from the Kevitsa Igneous Complex in Lapland, Finland was floated in a complex water matrix that mimics onsite process water. This ore is remarkably similar to the Merensky ore in South Africa, meaning …

An investigation into the impact of residual reagents on flotation in response to process water recirculation
… parameters used to determine effects were solid recovery, water recovery, copper and nickel mineral recovery, copper and nickel mineral grade, residual concentrations of collector and depressant pre and post flotation as well as particle settling of the tails. For all test conditions relative to …

ΒΕΛΤΙΣΤΟΠΟΙΗΣΗ ΤΗΣ ΕΚΧΥΛΙΣΗΣ ΛΑΤΕΡΙΤΩΝ ΜΕ ΘΕΙΙΚΟ ΟΞΥ
THE ATMOSPHERIC PRESSURE LEACHING OF NICKELIFEROUS LATERITES BY SULFURIC ACID IS AN ALTERNATIVE METHOD TO THE HIGH PRESSURE LEACHING. TWO TYPES OF ORES WERE STUDIED (SERPENTINIC, HEMATITIC) AND THE INFLUENCE OF VARIOUS PARAMETERS LIKE LEACHING TEMPERATURE, ACID CONSUMPTION, PULP DENSITY, PREHEATING …
