SRK’s October 2013 preliminary economic assessment for Colt Resources says only the plain flotation route is supported by testwork, at 87% recovery.
Red Eagle Mining’s October 2014 report on the Colombian project targets 96% gold recovery from 4.57 g/t feed, with provision to expand to at least 720,000 t/a and filtered tailings going to dry stack and mine backfill.
The Fording River Coal Operations (FRO) Technical Report outlines the recovery methods employed at the British Columbia facility. The process plant utilizes conventional processing equipment based on industry standards, focusing on gravity separation for coarser particles and flotation for finer fractions. The plant design includes a breaker for initial size reduction, followed by heavy media cyclones for coarse separation and a fines circuit utilizing water-only cyclones and reflux classifiers.

First Phosphate’s December 2024 preliminary economic assessment for its Québec property sets out a conceptual SAG-ball mill, LIMS and fatty acid flotation flowsheet, with throughput rising to an average 20,800 t/d from Year 5 and ilmenite still unresolved.
The September 2013 Updated Indicated Definitive Project (IDP) report for the Madaouela project, prepared by SRK Consulting for GoviEx, outlines the technical and economic basis for processing uranium ore from the Marianne and Marilyn deposits in Niger. The study evaluates three alternative treatment flowsheets, ultimately selecting Option 1B as the base case. This option incorporates crushing, radiometric ore sorting (ROS), wet milling, ablation, two-stage acid tank leaching, and enhanced solvent extraction using Cyanex 600. The design throughput is 4,020 tonnes per day, targeting a uranium production of approximately 2.24 million pounds of U3O8 annually.

The Gabbs Project employs a dual-processing strategy to recover gold, silver, and copper from oxide and sulphide mineralization. The initial five years of mine life will focus on heap leaching of oxide material, transitioning to milling and flotation for sulphide resources starting in year six. Both circuits share common crushing, SART, and ADR infrastructure to optimize capital and operational efficiency.

This technical report details the processing operations and metallurgical performance at the Ying Property, operated by Silvercorp Metals Inc. in Henan Province, China. The property currently utilizes two processing plants, Plant 1 (Xiayu) and Plant 2 (Zhuangtou), with a combined design capacity of 2,800 tpd and actual throughput averaging 2,500 tpd. A third processing plant (Plant 3) is under construction with a design capacity of 3,000 tpd, scheduled to begin trial production in mid-2024, which will replace the existing facilities.

This 2016 NI 43-101 Technical Report by Behre Dolbear outlines the Reno Creek ISR Project for AUC. The project proposes In-Situ Recovery (ISR) for uranium extraction from fluvial and shoreline facies sandstone formations. The report details the technical feasibility based on pilot tests and bench-scale studies, highlighting a recovery rate of approximately 70% of in-place resources.
The Williams Mill at the Hemlo Mine utilizes a conventional processing flowsheet designed for sulphide ore, incorporating crushing, grinding, gravity concentration, and cyanide leaching. The plant currently processes underground ore following the closure of the Williams open pit in 2020. The facility includes a gravity circuit with Knelson concentrators and an intensive leach reactor, followed by a Carbon-in-Leach (CIP) circuit for gold recovery. Tailings management involves a paste plant for underground backfill and a flotation circuit for sulphide removal prior to deposition in the Tailings Management Facility (TMF).
