MRA seeks suppliers for HDS pilot trials at three UK mine water sites.
The Mining Remediation Authority (MRA) is conducting preliminary market engagement for field-based High Density Sludge (HDS) pilot treatment trials for zinc-bearing mine waters at three UK sites: Threlkeld Lead Mines (Westmorland and Furness), Abbey Consols Mine (Ceredigion, Mid Wales), and a site in the Minsterley catchment (Shropshire). The trials aim to validate HDS treatment performance, establish optimized operating conditions, and generate data for potential full-scale schemes. Suppliers must provide containerized pilot plant, operate trials, and deliver technical reports. Requirements include proven experience in HDS trials for metal-contaminated mine water, particularly zinc-rich, net-acidic, or circum-neutral waters. The contract value is not disclosed, but the scope suggests a medium-scale, specialized engineering project.
