EnviroLeach Technologies Inc.'s (ETI:CSE; EVLLF:OTCQB) proprietary formula can extract palladium out of a multi-metal source and reduce it to an aqueous solution, it announced in a March 18, 2019 news release.
Specifically, on initial testing, the company's product recovered 90% of contained palladium from ceramic-based catalytic converters in about two hours' time. Electrowinning tests showed, on one sample, an 83% palladium recovery from a solution, which was achieved within 40 minutes.
The global automotive catalytic converter market report is expected to reach $183.4 billion by 2022, for a resulting CAGR between 2016 and 2022 of 7.7%, the release cited from an Allied Market Research report.
EnviroLeach will conduct further in-house testing to optimize chemistry and leach components, after which an external laboratory will evaluate them for validation.
Study also is being conducted on the use of EnviroLeach's technology to extract other platinum group metals, such as platinum. Testing on a pilot scale in that regard could take place in Q3/19 or Q4/19.
A news release from March 11, 2019 announced results of testing by the outside firm SGS on the ability of EnviroLeach's technology to extract gold. EnviroLeach contracted with this inspection, verification, testing and certification entity to conduct validation testing on its proprietary formulas.
SGS did the first set of leach tests on high-grade gravity concentrate tails and flotation concentrates. On tests using oxidized material resulting from autoclaving and roasting, the firm achieved more than 94% recoveries within two hours. It extracted 85% gold from the table tails and 90% from the flotation concentrate, both within 24 hours.
The second set of tests resulted in 96% recoveries on the autoclaved sample and 94% on the roasted sample, both within two hours.
"These positive, impartial test results are similar to hundreds of previous tests performed by our company and independent metallurgical labs all across North America," EnviroLeach Executive Vice President Ish Grewal said in the release. "These test results also highlight the accelerated leach kinetics using EnviroLeach formulas on both the autoclave and roasted samples."[NLINSERT]
