This paper examines new copper production from waste-grade ore using Blue Planet Strategies' DEMET™ (Dynamic Electrode Mining Effluent Treatment) technology, which aims to bridge the practical weak pregnant leach solution (PLS) processing gap in heap leach-solvent extraction/electrowinning (SX/EW) operations by electrochemically removing metals from weak streams and generating product streams strengthened in target metals in a functional analog to SX. Weak PLS treatment was studied and used to estimate the economic and production impacts for a representative hypothetical brownfield copper heap leaching and DEMET-augmented SX/ EW operation to utilize "waste ore." Copper removal at 86% plating efficiency to below 0.1 g/L copper with power consumption of 0.55 kWh/lb copper and product strengths of over 10 g/L copper are presented. Modeling yielded approximately $2/lb total copper production and = $1/lb treatment costs with an immediate operation gross margin increase of 12% for the augmented brownfield. Potential mine life extension with an average 38% gross margin on "waste ore" augmented production at copper values of $3.25/lb was also indicated.

DESCRIPTION (provided by applicant): Harmful metals not readily detoxified naturally are discharged from numerous industrial activities and pose lasting environmental hazards requiring expensive remediation efforts. This project targets profitable dilute metal removal and reclamation. Creating an economic driver for metal contamination mitigation improves human health by promoting environmental cleanups and stopping metal toxin discharge. This is particularly valuable for the many abandoned mines leaking toxic Acid Rock Drainage (ARD) Nation-wide and for which no economic incentive to correct presently exists (i.e. left to Superfund cleanups). Objectives: This work's long term goal is to change the environmental paradigm so waste is treated as a resource. The patent-pending platform technology was shown capable of profitable dilute copper recovery and a new variation for greatly expanding the technology's utility was recently validated. Here this new core technology variant will be used to profitability remove iron (a predominant contaminant) from Acid Rock Drainage (ARD) and recover it as a high- value product widely used in a variety of number of industrial processes. Expanding the target technology range of utility will facilitate market entry and magnify its overall positive impact. Specific Aims: Phase I goals include - Demonstrate the removal of dilute iron from synthetic ARD using the technology. Demonstrate the target high-value product recovery and generation from iron. Demonstrate conversion of diluteiron in synthetic ARD into the target high-value product. Test technology performance trends with ARD and select preferred operation parameters. Modify 10 GPM copper recovery prototype for iron removal - test at Superfund ARD site. Research Design and Methods: The proposed aims will be accomplished as follows: A 0.5 GPM bench-top ARD treatment cell incorporating the new concept will be constructed. Standard electrochemical laboratory batch and flow-through controlled voltage tests treating synthetic and real ARD will establish the technology performance trends. The targeted iron halve reaction progress will be monitored spectroscopically. Iron recovery and conversion, ARD treatment rate, system power consumption, plus physical and performance stability will be determined as a function of key operating parameters. Financial modeling using operating/performance trends estimates scenario treatment costs. Benefits: The targeted ARD iron removal improves traditional treatment and stretches tax- payer dollars. It defrays and reduces costs by lessening treatment loads and providing revenue. PUBLIC HEALTH RELEVANCE: Acid Rock Drainage (ARD) at abandoned mine sites contaminates thousands of miles of waterways and associated watersheds and is costly to mitigate. This project will improve public health by validating a new way to profitability remove iron from ARD and recycle it as a marketable high-value product widely used in industrial processes. By targeting iron, typically the most prevalent metal in ARD, the process developed here will find broad utility, have a significant societal impact, and provide excellent taxpayer return on investment.

Copper is a commodity essential to modern society and its production is very energy intensive. Half of U.S. copper consumption goes to electrical, heating, and plumbing infrastructure in building construction and energy use for copper production topped 43 trillion BTUs in the early 1990s. Currently the U.S. imports about 1/3 of the 2.6 billion pounds of copper used annually. This opens our economy to impact by geopolitical uncertainties as rapid modernization in China and India strain demand, elevate prices, and create supply uncertainties which will create strong headwinds to the U.S. economy for decades. Sadly, 1/3 of global copper ore cannot be economically utilized and the remaining 2/3 is rapidly running out. This is forcing producers to use lower grade and less accessible ore which drives up processing energy needs so that energy consumption for each pound of copper production is burgeoning. Blue Planet Strategies (BPS) has a patent pending technology allowing efficient and practical strengthening of weak metal laden streams. Applying this new platform technology to copper production remanufactures ore that is currently a waste into a viable production resource and valuable product stream. It also can reduce copper generation energy consumption by up to 50%! Enabling use of this abundant low-grade ore common to US mines will markedly raise domestic copper production while concurrently saving large amounts of energy for each ton of copper produced this way rather than through conventional means.Commercial Applications and Other Benefits: The BPS solution augments conventional copper heap leaching operations so that they can cost-effectively produce copper from abundant but currently unusable ore. This will greatly extend active mines times to depletion, can double production at existing operations, and provides the key to unlock 1/3 of the global copper reserves. Such BPS-enabled copper production will stabilize domestic copper supplies and prices, create high-paying jobs, and inject significant revenue into local economies while reducing the Nations reliance on copper imports. This solution also reduces copper minings overall carbon footprint and will save tremendous quantities of coal and diesel fuel through the energy savings realized. The technology also holds promise for use in the production of other metals.
