EnviroLeach Announces Results of Process Enhancements and Vancouver Facility Construction

17.07.2018 | 11:00 Uhr | GlobeNewswire

VANCOUVER, British Columbia, July 17, 2018 -- EnviroLeach Technologies Inc. (the “Company “or “EnviroLeach”), (CSE:ETI) (OTCQB:EVLLF) (FSE:7N2). is pleased to announce that new upgrades and enhancements to the EnviroLeach process has yielded positive results in a series of bulk tests.

The modifications and enhancements to the EnviroLeach process, which included the addition of a proprietary 3 stage concentration process and minor formula modifications, have delivered significant improvements in performance and recoveries.

The benefits of these enhancements include:

  • Improvements in the overall recoveries of precious and base metals to over 90%
  • The production of a refinery-grade, saleable concentrate
  • Reduction of formula/chemistry losses to in-leach contaminants
  • 50% improvement in process flow and feedstock throughput
  • Advancements in the mechanical processes including grinding, pumping, filtration and agitation
  • Improved leach kinetics and characteristics
  • Increased process pulp density from 10% solids to 25% solids
  • Extended reusability of the formula
  • Improved gold electrowinning characteristics
  • Improved base level economics
  • Reduced environmental footprint

The company has completed several lab to pilot scale and full-scale tests to confirm the results of these modifications on various low to mid-grade circuit boards with positive results. The latest 3.0 tonne bulk test yielded the following results:

Element Head Sample Light Fraction Heavy Fraction (Concentrate) Combined
Grade Grade Distr. Recovery Grade Distr. Recovery
Au 250 g/t 185 g/t 44 % 80 % 400 g/t 56 % 99 % 91 %
Ag 1,000 g/t 3.3 g/t 2 % 0.25 % 2,450 g/t 98 % 96 % 94 %
Pd 72 g/t 20 g/t 17 % 40 % 150 g/t 83 % 94 % 85 %
Cu 22 % 7 % 14 % 80 % 81 % 86 % 96 % 94 %
Average Overall Recoveries: 91 %

The results of the bulk testing indicate that the gold (Au) is almost evenly distributed between both the heavy (56%) and light fractions (44%) with all other metals predominantly reporting to the heavy (Concentrate) fraction. The resulting concentrate represents approximately 30% of the original mass with copper grades in the plus 80% range, gold at 400 g/t, silver at 2,450 g/t and palladium at 150 g/t. The light fraction has a gold grade of 185 g/t with recoveries in the EnviroLeach solution in the plus 80% range.

The Company is also pleased to announce that its partner, Mineworx Technologies, has leased a 13,674 sq. ft. facility in Vancouver (Surrey), BC to construct and assemble a 20 tonne per day E-Waste concentrate plant. Both companies are preparing the facility for the arrival of the primary process equipment from their world-wide suppliers. All necessary components are scheduled to arrive between August 1st and August 15th. Testing is scheduled to begin on September 1st with the commencement of half-scale production on October 1st.

The company is currently securing its first 100 tonnes of printed circuit board (PCB) feedstock for initial testing. It is anticipated that the facility will produce a high-grade concentrate which will be sold to a USA based refiner and the resulting light fraction will be sent to the Memphis facility for processing.

Duane Nelson, CEO, states: “I am very pleased with the recent bulk sample results as they exceeded our expectations. We are confident we can replicate these results in our first 20 tonne per day concentrate plant currently under construction.

The operational challenges and delays we faced at the Memphis facility were predominantly process based and were exacerbated by high levels of metal in the feedstock. Our team has developed a unique new concentration process which extracts over 80% of these metals into an almost pure metal concentrate which resolves the process issues and dramatically enhances operational performance and economics.

Both the EnviroLeach and Mineworx teams’ continued ability to overcome the pioneering challenges we face in this relatively new sector has been outstanding. The team’s extensive experience in conventional mining, chemistry and metallurgical processes have proven to be quite valuable in this fusion of technologies.”

About EnviroLeach Technologies Inc.

EnviroLeach Technologies is a technology company and near-term gold producer that is engaged in the development and commercialization of environmentally-friendly formulas and technologies for the treatment of materials in the mining and E-Waste sectors. Using its proprietary non-cyanide, non-strong acid water-based, near neutral pH treatment process, EnviroLeach extracts precious metals from ores, concentrates, and E-Waste using only FDA approved additives to ambient temperature water.

Backed by the momentum of a first-class staff of scientists and engineers, tens of thousands individual assays, independent validations and strategic partners, EnviroLeach’s technology will become the standard for the provision of eco-friendly methods for the hydrometallurgical extraction of precious metals in both the conventional mining and E-Waste sectors.
