Client JGC Japan

Project Shale Oil Molybdenum and Vanadium Recovery Project


Project Overview

JGC Japan approached Sargon Engineering seeking advice on how they might capitalise on a body of oil shale residue containing valuable quantities of molybdenum (Mo) and vanadium (V). After researching current market trends, Sargon Engineering prepared a preliminary market assessment based on the composition of the client’s resource, illustrating the feasibility of extracting saleable minerals. Sargon Engineering was also invited to comment on the process route that might be employed to exploit the deposit.

Solutions Delivered

Sargon Engineering adopted an approach whereby vanadium and molybdenum would be appraised separately. Sargon Engineering supplied JGC with recent literature and reports explaining the functioning of world vanadium markets and the various contingencies which determine success in the industry. Based on previous experience with molybdenum containing compounds, Sargon Engineering was able to suggest the likely compounds which might be found in their shale oil deposit, and which of these hold a definite market worth, namely the calcines of molybdenum concentrates. The potential for the formation of MoS2 was considered, and the subsequent potential for flotation concentration. This concentrate might then be used directly for ferromolybdenum production or further purified by leaching to extract molybdenum metal. In lieu of detailed testwork, Sargon Engineering provided three process solutions for the client’s consideration.

Notable Results

Sargon Engineering contributed valuable insights and considerations which increased the client’s understanding of the nature of the resource they had on hand. The engineering work was completed within the allocated budget.
