American Manganese begins pilot plant testing for low cost EMM production
Welcome to another episode of resourceINTELLIGENCE’s inSITE report. This is a very special episode for investors who are seeking to broaden their understanding of mining processes while taking a peek at one of the foremost electrolytic manganese (EMM) plays in modern history—American Manganese (TSXV: AMY).
American Manganese—with the help of Kemetco Research and some very creative thinking—have managed to produce what could be the lowest cost EMM in the world. Today we’re going to be visiting the pilot plant where resources from American Manganese’s Artillery Peak project in Arizona is processed into EMM and EMD. It’s a giant, patent-pending-leap forward for the company, which has manganese resources of 14.9 billion pounds indicated and 3.5 billion pounds inferred. That’s a lot of manganese. This is also a very big deal considering that manganese is the 4th most consumed metal in the world.cv To some investors, “grade is king”, but not so for American Manganese. Ironically, the company has unlocked a way to produce manganese metal from low-grade resources at a lower per pound cost than just about any high grade deposit in the world.To do that, American Manganese’s CEO, Larry Reaugh, hired Kemetco Research out of Vancouver, BC, to solve an age old problem: How to create a closed circuit process where water and power are recycled rather than wasted.Kemetco’s breakthrough, it turns out, is up to 12.4 times (or 1,139%) more energy efficient in its water recovery than conventional methods in low-grade manganese mining. This dramatically lowers the overall cost of production.THE KEMETCO PROCESS: Up to 12.4 times more energy efficient.
This low-cost process includes several steps that use existing technologies and one high tech step that leads to incredible cost savings.
First the resources from the Artillery Peak project—which is already very brittle or friable—is crushed. Then in the plant, the metals are leached from the crushed resources… the resulting solution is thickened and solid waste is separated from the metals solution.
The solid waste is then rinsed and cleaned in the Counter Current Decantation (CCD) process while the mineralized or Pregnant Leach Solution (PLS) is purified, mixed with sodium carbonate. Finally the manganese metal is consolidated into pure manganese plates in an electrowinning circuit.
You’d think that was the end, but it’s not,…
