D-Solve uses biology to strip impurities out of your concentrate inside the flowsheet you already run, recovering more of the metal that’s in the ore you’re already mining.
D-Solve is a bolt-on process that uses targeted biology to dissolve the impurity minerals, the gangue, that travel with your valuable metal through the flowsheet. Remove the gangue and two things happen at once: the concentrate grade goes up, and metal that conventional processing would have lost in tails is recovered instead.
At the center of it is the Allonnia Biosolution™, a biologically derived solution selected and engineered to go after specific impurity minerals while leaving the metal you’re after untouched. That selectivity is the whole point, and it’s where conventional chemical and mechanical separation processes have reached their limits. D-Solve has demonstrated results on nickel, copper, and molybdenum concentrates, with lithium, zinc, and iron in active screening: the critical minerals the energy transition runs on.
Pull more payable metal from ore you’re already processing. By dissolving the impurity minerals that lock up your concentrate, D-Solve recovers metals that conventional processing sends to tailings.
A cleaner concentrate earns better terms. Stripping out gangue raises the grade and removes penalties like arsenic, lead and fluorine, so more of the mass leaving your site is the metal you actually sell.
Ore zones too high in impurities to process economically today come back into play. Handling those impurities biologically extends the life of a deposit you’ve already permitted, developed, and paid for.
D-Solve works alongside the plant you already run. No flowsheet redesign, no capital rebuild, no waiting years for new infrastructure to come online.
Removing impurities with biology displaces energy-intensive mechanical processing. Less energy and less carbon per tonne of metal follow from how the process works, not from a trade-off against performance.
Fewer penalty elements at the smelter, less waste mass to transport, and more metal per tonne add up to a stronger margin on ore you’re already moving.
D-Solve runs as a self-contained loop between stages you already operate. The Biosolution does the work, then regenerates and goes back to work, so the process keeps running on the same charge.
Your concentrate meets the Allonnia Biosolution™ in a stirred reactor. The biology selectively dissolves the target impurity minerals into solution and leaves the valuable metal in the solids, where you want it.
The upgraded concentrate, now cleaner and higher grade, is separated from the impurity-laden liquid using conventional equipment. The solids move on through your flowsheet; the liquid carries the dissolved impurities away.
The spent liquid is processed to strip out the captured impurities and restore the Biosolution, which returns to the front of the loop. Regenerating and reusing the biology is what keeps operating cost and waste low, run after run.
Eagle Mine, in Michigan, is the only active nickel mine in North America. The first mobile D-Solve unit was deployed and operated there through a completed pilot.
D-Solve isn’t a concept waiting on its first trial. The process has run on real concentrate, at a working mine and in continuous demonstration, with the safety and performance record to back it.

What D-Solve does at one site, it can do across an industry: lift production from ore already being mined, cut the energy and carbon spent getting metal out, and turn low-grade and penalty-laden material into value. Proven at pilot, the next step is scale.
