Project Overview

Client WorleyParsons/ SMR

Project Skopin Molybdenum and Ferromolybdenum Process Plant Study, Russia

Project Overview

SMR is a Russian mining company which formed an alliance with WorleyParsons for the re-development of the metallurgical complex at Skopin in the Ryazan oblast (county). Sargon Engineering was engaged to provide process engineering review of the flowsheet proposed for processing molybdenite concentrate from SMR’s mines in the Khakassia region of Siberia.

Solutions Delivered

A thorough review was undertaken of the process technology and economics including:

  • Risk review of pressure oxidation and product recovery system
  • Metsim modeling and costing of pressure oxidation and roasting options
  • Review of pilot plant testing carried out at Gipronikel in St. Petersburg
  • Capital and operating cost estimates for pressure oxidation and roasting options
  • Modeling and costing of roaster off-gas scrubbing options
  • Layout for a ferro-molybdenum production line
  • Review of concentrate pre-treatment processes eg copper removal

Notable Results

Improved understanding of economic drivers in the production of molybdenum chemicals.
