Simple, Low Capex Start-Up
A Simple Process for First Production
Test work during the recently released Pre-Feasibility Study highlighted an opportunity for a low capital and operating cost beneficiation plant to produce medium grade manganese lump concentrate as part of a staged Project ramp up.
The design philosophy has utilised predominantly mobile or semi-mobile equipment such that operating installation maintains a degree of flexibility for management of the advancing mining face, whilst minimising civils, structure and set-up investment costs.
The proposed processing facility includes is shown schematically below and utilises readily available plant and equipment and a very simple process.
Downstream Processing Breakthrough
Element 25 ultimately wants to build a hydrometallurgical processing facility to undertake downstream processing on site to produce high purity manganese products.
A new process flowsheet developed for the unique Butcherbird ores means that they can be leached into solution at ambient temperature and atmospheric pressure with high level of selectivity and very rapid leach kinetics with approximately 95% of the manganese extracted in around 30 minutes to produce a high purity manganese solution.
This liquor is then further purified and either put through a crystalliser to produce high purity manganese sulphate for use in lithium ion battery cathodes or put through an electrolysis plant to produce electrolytic manganese metal both of which represent high purity high value manganese products.
Simpler, cleaner proprietary processing method.
A cleaner, lower carbon flowsheet coupled with high penetration renewable energy place Butcherbird at the forefront of sustainable metal production.
