VANCOUVER, BC / ACCESSWIRE / February 13, 2020 / Vancouver, BC, February 13, 2020, EnviroLeach Technologies Inc. (the "Company "or "EnviroLeach"), (CSE:ETI) (OTCQB: EVLLF) (FSE:7N2) is pleased to announce it has completed preliminary lab-scale testing on the recovery of tin metal from printed circuit board (PCB) material.
Hydrometallurgical studies conducted at Enviroleach's lab resulted in recoveries of approximately 90% of the tin contained in the tested PCB material.
The current treatment of PCBs involves the recovery of metals by smelting and is focussed on the recovery of gold, silver, palladium and copper. These smelters do not pay for the contained tin, yet it makes up a significant proportion of the overall potential economic value of the PCBs. Typically, the tin content in printed circuit boards range from 1% to 6% of the total weight. These percentages translate to a contained gross value of $170 to $1,020 per tonne of PCBs based on a tin value of $17.00 per kilogram.
The recovery of tin has the potential to give the EnviroLeach process a distinct economic advantage. It may also provide the only sustainable, recurring resource of tin from waste PCBs, resulting in a substantial contribution towards the achievement of the global circular economy.
Over the past decade, ∼52% of all refined tin has been used as solder in the electronics industry. Although current global tin reserves can meet the short-term demand, for long-term sustainable development, recycling tin from secondary resources, such as PCBs, is essential.
As previously announced in a news release on January 15, 2020, the Company is seeking warrant holder approval to amend the terms of 6,700,000 outstanding warrants from a $2.50 exercise price and March 1, 2020 expiration date to a $1.33 exercise price and September 30, 2020 expiration date.
