CONVENTIONAL MANGANESE RECOVERY PROCESS ONLY ECONOMICAL WITH HIGH GRADE Mn ORE > 40% Mn !
•EXTENSIVE MILLING REQUIREMENTS
•ROASTING – ENERGY INTENSIVE
•DUST HANDLING REQUIREMENTS
•LOW RECOVERY OF Mn
That grade comment alone should make it so clear as to how impressive it is what Kemetco came up with. Kemetco used 3% grade and AMY is ( unbelievably ) less than half the cost to produce EMM world-wide.
AMY has done the impossible.
And this goes with above......
GOALS FOR ECONOMICAL RECOVERY FROM LOWER GRADE RESOURCES
•Minimize Milling Requirements
•Avoid High Temperature Roasting Requirements
•Improve Extraction of Mn from Resource
•Efficient Recovery of Water
•Economic Destruction of Un-Wanted By-Products
•ENVIRONMENTAL CONSIDERATIONS – GREEN PROCESS
That's 6 things AMY set out to do.....all 6,,,,check.
"one of a kind "
