en.Wedoany.com Reported - On March 30, Vancouver-based RZOLV Technologies of Canada and Australia's EMEW Clean Technologies announced a strategic alliance to develop an integrated system for extracting precious metals (such as gold and silver) and critical metals from mineral concentrates and recycled materials without using traditional cyanide processes. The collaboration combines RZOLV's water-based extraction technology with EMEW's electrowinning platform, aiming to provide the mining and recycling industries with a low-environmental-impact metal recovery solution.
RZOLV Technologies contributes a patent-pending, non-cyanide, water-based dissolution platform capable of selectively dissolving target metals from refractory feedstocks like complex sulfide ores and tailings. EMEW Clean Technologies brings over 30 years of experience in electrowinning technology, which can recover high-purity metals from solution streams with recovery rates exceeding 99% in some applications. EMEW has offices or facilities in six countries, including Australia, Canada, India, Ireland, Dubai, and Mexico, boasting established global marketing channels and a customer network spanning precious metal recovery, electronic waste processing, and battery recycling.
According to the agreement reached on March 30, the initial focus areas for the collaboration include: precious metal concentrates, refining operations for crude metal ingots, mining solutions, tailings reprocessing, and selected secondary feedstocks (such as electronic waste and spent batteries). The partners plan to bring the integrated system to market through technical validation and process optimization. RZOLV President and CEO Duane Nelson stated that a complete processing solution creates greater value for customers than a single reagent technology; EMEW CEO Ian Ewart noted that market trends are moving towards greater selectivity, higher on-site recovery rates, and stronger environmental performance, and that their combined technologies align with this demand.
Traditional cyanide heap leaching and smelting processes face increasing regulatory pressure and environmental controversy, prompting mining and recycling companies to actively seek alternatives. RZOLV's water-based dissolution system avoids the toxicity and legacy liability issues associated with cyanide, while EMEW's electrowinning platform can convert dissolved metals into high-purity products. This collaboration provides RZOLV with downstream recovery technology and established customer relationships, accelerating its commercial deployment; EMEW gains a differentiated upstream chemical process, broadening the range of feedstocks its electrowinning systems can handle. With the growing volume of global electronic waste and the expansion of battery recycling infrastructure, this integrated technology is expected to help operators increase on-site value capture, reduce reliance on third-party smelting and refining, and expand the types of materials that can be processed responsibly.
