TORONTO, June 01, 2023 (GLOBE NEWSWIRE) -- EnviroGold Global Limited (CSE: NVRO | OTCQB: ESGLF | FSE: YGK) (“EnviroGold Global” or the “Company”), a Clean Technology Company accelerating the world’s transition to a circular-resource economy, is pleased to announce that it has signed a memorandum of understanding with Hindustan Zinc Limited (NSE: HINDZINC) (“HZL”), a US$15+ Billion listed company and India’s largest zinc and silver mining company and Runaya Green Tech Limited, a subsidiary of Runaya Refining LLP (“Runaya”) to evaluate the EnviroGold Global metal recovery process on the waste streams from various HZL operations.
HZL operates zinc, lead and silver mines and smelters across India and Runaya is engaged in the processing of mineral residue for recovery of various metals and chemicals. It is intended that Runaya will be a business partner of HZL for execution and operation of the feasible outcome of this project.
The initial testing, that will be completed at the EnviroGold Global Laboratory near Brisbane, Australia, will focus on the recovery of silver and zinc from the Jarosite and Jarofix wastes, which are generated from HZL’s smelting operations and stockpiled at its various sites. There are about 7 million tonnes of these wastes. In addition to these high-grade wastes, the HZL operations produce over 0.5 Mt of Jarosite annually (Guidelines for Handling and Management of Jarosite Generated from Zinc Manufacturing Plants, Ministry of Environment, Forests & Climate Change, Government of India). EnviroGold Global expects that a modification to the current process that is being tested in the ALS laboratory in Perth Australia will be amenable to the recovery of these metals.
EnviroGold Global has already received the Jarosite and Jarofix wastes materials for the initial testing at its laboratory. It is expected the initial testing will take 2-3 months to complete.
