Name of the Project
Renison tailings retreatment project (Rentails).
Location
The project will be located about 1.5 km north-west of the existing Renison tin concentrator, in Tasmania, and adjacent to the existing tailings storage facility.
Client
Rentails, in which Metals X owns a 50% share through the Bluestone Mines Tasmania Joint Venture.
Project Description
Renison produces about 7 000 t/y of tin in concentrate.
The project proposes to expand production by about 5 400 t/y of tin and 2 200 t/y of copper through the reprocessing and recovery of tin and copper from the existing historical tailings at Renison. This is based on the retreatment of about 21.6-million tonnes of historical tailings reserves at an average grade of 0.45% tin and 0.23% copper.
The project will have a mine life of about 11 years at a two-million-tonne-a-year treatment rate, with the opportunity to treat additional tailings and intermediate seams. The flow sheet comprises grinding, sulphide flotation, ultrafine gravity separation, tin flotation and tin fuming.
