Abstract

The purpose of this project was to determine the viability of different revenue streams for Nth Cycle’s core electrochemical refining technology, particularly in the extraction of non-precious metals such as copper, tin, nickel, and zinc. Although these materials are essential for electric vehicles, wind power, and broader electrification, much of the world’s refining remains concentrated overseas, creating supply-chain, geopolitical, and environmental risks. At the same time, valuable metals remain locked in batteries, scrap, and other waste streams, while conventional refining processes are costly, carbon-intensive, and slow to build.

To address this gap, Nth Cycle has developed an electro-extraction method and implemented it with their core system known as the “Oyster”. Rather than relying on large, centralized refineries, the company’s system can be deployed at recyclers, manufacturers, and mines to recover high-purity metals from waste streams and ore. In effect, Nth Cycle aims to localize and decarbonize mineral refining by offering a cleaner, more flexible alternative to traditional processing infrastructure.

Nth Cycle’s pilot site is in Fairfield, Ohio and this plant’s current focus is the intermediate refinement of mixed hydroxide precipitate or MHP which is partially refined form of nickel-cobalt essential in battery cell production. While Nth Cycle recently secured a $1.1 billion offtake agreement with Trafigura, a commodity firm, the company is still young and looking to identify additional market opportunities for its electro-extraction method. It is this goal that guided the following research into alternative uses for the company’s electro-extraction method. Initial planning and goals were set in early January of 2026 after identifying copper mining and electroplating. Analysis and feedback were ongoing from February to April and adjusted accordingly. The main partner and point of contact for this was Alexander Allen, the current Vice President of Corporate Development at Nth Cycle. The findings from the mining analysis showed that Nth Cycle’s core technology was cost competitive by equivalent production capacity but significantly constrained by the necessary processing volume of raw ore for a conventional mine. Despite this, the findings also indicate that the competing technology of conventional electrowinning does not greatly benefit from increased capital efficiency as the scale of production increases beyond the median sized mine within the study’s sample. Mining adjacent bleed streams may be viable and cost competitive at the Oyster’s current capacity of 3000 tons annually but this depends on concentration and volume and requires further investigation and analysis.

The findings from the electroplating analysis showed multiple barriers to entry for Nth Cycle. First, the revenue generated by the typical electroplating company within the United States is not high enough to cover the costs of Nth Cycle’s current Oyster system. Second, the scale of the Oyster is not compatible with most electroplating company warehouses which are comparatively small. Third, the competitive landscape for similar metal particulate extraction technologies is fierce and competitors benefit from industry recognition, better pricing, and appropriate sizing and scale. Finally, the regulations and costs of hazardous waste processing are not high enough to be a value proposition.
