Ada Tepe, Bulgaria’s first greenfield mine in over 40 years, has completed open-pit gold production and moved into rehabilitation, using dry-stack tailings and paste backfill to minimise conventional wet tailings storage. The Dundee Precious Metals operation was designed with filtered tailings deposition on a lined facility, progressive reclamation of waste rock dumps, and strict water recycling to limit discharge to local catchments. Its closure approach, including reshaping benches and re-vegetation to blend with the Rhodope Mountains terrain, is being positioned as a reference model for future EU mine waste projects.

Valmet slurry flow specialist Juha Häkkinen sets out how flotation performance hinges on stable level control, correct valve sizing and consistent aeration across conventional cells, columns and flash flotation circuits. He focuses on control-valve behaviour in slurry duties, including cavitation, erosion and hysteresis, and how poor valve selection destabilises froth depth and air–slurry mixing. The piece points to tighter valve control and tailored trim designs as practical levers to improve recovery and reduce reagent overuse in brownfield flotation plants.

Epiroc has agreed to acquire France-based Aramine SAS, a specialist supplier of spare parts and related services for underground mining equipment headquartered in Aix-en-Provence. Aramine brings more than 50 years of underground mining experience, a workforce of about 65 employees and a global customer base spanning over 70 countries. The deal signals Epiroc’s push to deepen its aftermarket footprint, particularly in spares and service support for underground fleets where lifecycle costs and parts availability are critical.
