Multicom Fact Sheets for St Elmo Vanadium Project
https://www.mcres.com.au/latest-news
FACTSHEET Newsletter #1 Saint Elmo Project September 2018
‘The Project will use proven processing technology which includes a pressure/temperature leach followed by the traditional vanadium pentoxide recovery process including solvent extraction, desilication, ammonium metavanadate (AMV) precipitation and de-ammoniation.’
FACTSHEET Newsletter #3 Saint Elmo Vanadium Project February 2019
‘A Water Supply Strategy has been undertaken to understand alternate sources of water including current or proposed water sources in the region. This strategy also considered options which may have broader potential benefits to Julia Creek and surrounding communities, including other potential users in the North West Minerals Province. Details will be confirmed following additional studies. At the same time, Multicom’s engineering team have assessed the processing options to improve the efficiencies of water use where possible. Currently, both pressure leaching and heap leaching processes are being considered, with both options addressed in the EIS.'
Note that heap leaching has only been included in the most recent Multicom factsheet….this February!
Something has happened between September and February, probably with the public consultations to make them think twice about methodology?
Because of the sensitivity of the water suppies in the area, have they been forced to take the heap leaching seriously as a more environmentally friendly option?
So does heap leaching use less water than pressure leaching?...is this the issue they are looking at or is used water more easy to treat using one or other of the processeses?
Either way, heap leaching at leasts SUGGESTS (to me anyway) less water and easier to treat used water.
Initially, 10,000tons per year!
IMO we could win this contract!
