CHARACTERISATION OF PARAMETERS INFLUENCING THE PHASE SEPARATION IN COPPER SOLVENT EXTRACTION SYSTEMS USING OXIME-TYPE EXTRACTANTS FOR THE FIELD OPERATION

Solvent extraction (SX) is one of the most widely applied hydrometallurgical processes in copper production from oxide ore.As the high-grade ore deposits have been developed and depleted, now only low-grade ore deposits are being developed and are therefore facing obstacles of extreme processing conditions.This results in leaching gangue minerals a

Tourism has been one of the fastest growing industries and it makes important contributions on economies.Based on this, the literature aims to determine the factors affecting tourism demand behavior.In this paper, we analyze the effect of economic policy uncertainty (EPU) on both total and personal outbound travel expenditures in the panel data of
