BacTech Advances Zero Waste Patent for Pyrrhotite
BacTech Secures Funding to Advance “Zero-Waste” Patent for Pyrrhotite
Toronto, Canada, July 12, 2024.
BacTech Environmental Corporation (“BacTech or the Company”), (CSE:BAC,
OTCQB:BCCEF) today announced that it has reached an agreement to vest a 10% stake in a
“zero-waste” patent for treating pyrrhotite and pyrite tailings using bioleaching to an investor
group for Cdn$100,000.
As part of the ongoing MIRARCO piloting study, this will enable the technology to be further
developed to full patent status along with preliminary process modeling work required for a
conceptual design of a demonstration plant. As part of the larger MIRARCO study, BacTech has
committed $100,000, which is sufficient to meet its obligations.
A BacTech "zero-waste" preliminary patent, which is to be finalized by April of next year, aims
to generate a portfolio of saleable products from re-treatment of tailings near Sudbury, Canada.
This technology produces products from materials that otherwise would have no value and report
as waste to create an environmental liability. With this new approach, incentives are added to
encourage investment in re-treatment and rehabilitation projects, in part by diversifying revenue
streams and risk to treat wastes containing subeconomic metal values while also remediating the
environment.
BacTech's Vice President of Metallurgy and Bioleaching, Dr. Paul Miller, stated “With the
advent of complementary technology and a dramatic increase in the prices of the underlying
elements that constitute pyrrhotite, we have a strong foundation for delivering economic benefits
from bioleaching sulphide tailings.”
For many years low grade nickel pyrrhotite was mined alongside pentlandite in the Sudbury
mining camp only to see it separated and deposited as waste in lakes to eliminate the rapid
oxidation of this very volatile sulphide mineral creating toxic environmental issues. The zero-
waste technology can also be applied to the treatment of other iron sulphide minerals, such as
pyrite, which often contain low value metals but are difficult to process economically.
The patent details the process of using bioleaching first to make the elements of pyrrhotite
soluble followed by a unique combination of downstream processing steps that interface
effectively with the iron industry by producing intermediate iron for steel or battery production,
as well as producing ammonium sulphate fertilizer for sale. Nickel and cobalt contained within
the mixed precipitates will be precipitated out as saleable commodities. This will provide an
additional revenue stream while smaller amounts of separated magnetite will also be sold. The
remaining silicate residue will either be used as backfill material or can be mixed with
geopolymers to form construction materials.
BacTech has filed preliminary patent applications earlier this year, with the final application to
follow the completion of the test work. In the 1990s, BacTech conducted a pilot plant at Radio
Hill, Australia, to separate metals from solution from pyrrhotite tailings but the existing
technology was not economical viable at the time.
BacTech will provide updates on the progress of the test work as results become available.
About BacTech Environmental Corporation
BacTech Environmental Corporation is a company that specializes in environmental technology.
We use a process called bioleaching to recover metals like gold, silver, cobalt, nickel, and copper,
while also safely removing harmful contaminants like arsenic. This process is eco -friendly and
uses naturally occurring bacteria that are safe for both humans and the environment. By using our
proprietary method of bioleaching, we can neutralize toxic concentrates and tailings while also
creating profitable opportunities. The company is publicly traded on several stock exchanges,
including the CSE, OTCQB, and Frankfurt Stock Exchange.
