Martin Engineering is promoting engineered solutions for silo, hopper and chute blockages to replace manual methods such as vessel entry and hammering walls, which expose workers to falls, engulfment and impact. The company typically applies external flow aids like air cannons, high-frequency vibrators and retrofit liners on chutes and spouts to break compacted material bridges and rat-holes without confined-space entry. For mine operators, the approach targets reduced unplanned downtime on conveyors and storage vessels while tightening compliance with lockout/tagout and confined-space regulations.

SiTration and BHP have launched two pilot deployments at the historic Copper Cities site in Arizona’s Globe-Miami district to trial SiTration’s copper valorisation technology on legacy material. The programme starts this month with a small-scale pilot focused on validating continuous, autonomous copper production, targeting low-grade or previously uneconomic resources. If successful, the approach could offer a route to recover additional copper from historic waste streams at similar brownfield sites without major new excavation.

Metso has secured orders from GR Engineering Services to supply key minerals processing technology for Develop Global’s Yitirrti copper-zinc-silver project in the Pilbara, Western Australia. The package includes crushing and grinding equipment and downstream process units for a new concentrator designed for moderate-scale copper-zinc-silver throughput, with flowsheet engineering led by GRES. For engineers, the deal signals continued preference for Metso’s integrated comminution and separation solutions on greenfield base metals plants in Western Australia’s hard-rock conditions.
