    Evonik–University of Guanajuato mining chemistry JV: process-water impacts for engineers

    First reported on International Mining – News

    30 Second Briefing

    Evonik has formed a strategic partnership with the School of Mining at the University of Guanajuato in Mexico to develop next‑generation sustainable, lower‑toxicity reagents for mineral processing. The collaboration centres on Evonik’s biosurfactant platform, targeting replacement of conventional petrochemical surfactants in flotation and related unit operations to cut ecotoxicity and improve biodegradability. For mine operators, this points to future options for meeting stricter water‑quality and tailings‑discharge limits without major flowsheet changes.

    Technical Brief

    • For other mining operations, such biosurfactants could support compliance with tightening regional discharge and toxicity standards.

    Our Take

    Mexico appears frequently in our mining coverage for precious and base metals like gold, silver and copper (for example at Torex Gold Resources’ Morelos complex), so Evonik’s sustainable chemistry work there is likely to be tested quickly against active, high-grade operations rather than only in laboratory settings.

    Evonik’s involvement in a JV structure in Mexico positions specialty chemical suppliers closer to mine design decisions; in our database, such early-stage chemistry input often correlates with later adoption of reagent packages that can reduce water and energy intensity in complex orebodies.

    Modern Mining’s US e-waste expansion: process, recovery and supply notes for engineers

    Modern Mining is preparing to commercialise its Greenville, North Carolina e-waste plant, which shreds, gravity-separates and then uses “aqueous purification” chemistry to recover gold, silver, palladium and copper without large-scale incineration or new smelting capacity. The move comes as President Trump’s July use of the Defense Production Act enables export restrictions on industrial waste containing critical minerals, aiming to keep higher-than-ore-grade electronic scrap within US borders. Modern Mining plans a distributed network of modular plants—targeting roughly one new facility per year over five years—to build a domestic secondary-metals supply chain alongside conventional mining.

    Gold price shakes off profit taking: planning signals for mine project teams

    Gold for December delivery on Comex rose 0.3% to $4,435/oz after rebounding from $4,365.50 and nearing $4,454.60 intraday, as softer July US inflation cut money-market odds of a September Fed hike to about one in three from over 40% a week earlier. Spot gold steadied around $4,353/oz and silver futures at $65.13/oz left silver down about 8% year-to-date, while BMI now expects gold to average $4,400/oz in 2026 with the dollar index in a 98–102 range. Precious metals miners have surged, with Hecla, Eldorado, Equinox, Coeur, Agnico Eagle and Newmont up 26–32% over ten sessions against an 8% move in gold.

    Copper price near record: LME warehouse squeeze and project signals for engineers

    Copper is trading near a record $14,500/t as the LME August contract’s premium over September blows out to $370/t and cash-to-three-month spreads hit $434/t amid a 42-day drawdown in exchange stocks to 204,975 t, nearly half already earmarked for withdrawal. Traders are diverting metal to the US ahead of potential 15–30% tariffs on refined copper and to China as smelters cut output following the DRC’s concentrate export ban, while Chilean supply remains constrained around 5.5 Mt/y and Indonesia’s 342,000 t/y Gresik smelter is offline. BMI now pegs 2026 prices near $13,500/t with “strong upside risks”, as shorts on the LME face the prospect of a warehouse bidding war.
