This section of the 2014 Hannukainen Technical Report details the metallurgical testwork and process plant design for the Hannukainen project. The ore bodies, including Laurinoja, Kuervaara, and Vuopio, contain magnetite and chalcopyrite with associated gold. Metallurgical testing conducted by SGS and GTK between 2007 and 2013 established a flowsheet involving primary AG/SAG grinding, copper flotation, magnetic separation, and pyrite/pyrrhotite flotation. The plant is designed for 6.5 Mtpa throughput at Rautuvaara, producing magnetite concentrate (68% Fe) and copper concentrate (25% Cu).

This technical report details the recovery methods and mineral processing plant design for a silver-lead-zinc sulphide ore project developed by Xtierra Inc. The facility is designed for a throughput rate of 2,000 tonnes per day (tpd). The processing circuit is engineered to produce separate lead-silver and zinc concentrates for off-site transport, utilizing a comprehensive flow of crushing, grinding, and flotation operations.

This Technical Report and Preliminary Economic Assessment outlines the proposed recovery methods for the Da Tambuk Project located in the Adyabo Property, Tigray National Regional State, Ethiopia. The project involves an underground mining operation targeting gold-silver bearing material. The proposed processing facility is designed to treat material at a nominal rate of 550 tonnes per day (200,000 tonnes per annum) using whole mill feed cyanide leach technology. The process integrates conventional crushing, ball mill grinding, gravity concentration, and a six-stage Carbon-in-Leach (CIL) circuit to recover gold and silver into a doré product.

The Cabaçal Project recovery methods utilize a conventional sulphide processing route designed for a nominal throughput of 6,850 t/d. The process includes primary crushing, semi-autogenous grinding, gravity concentration for gold recovery, and a multi-stage flotation circuit for copper-gold concentrates. The overall process design was selected based on thorough testwork analysis and is typical for this industry.

This technical report outlines the recovery methods proposed for the Rionegro project operated by Alicanto. The current beneficiation process is primarily hydro-gravimetric, utilizing water as the sorting element in both mine and camp conditions. Free gold is separated using gravity methods including washing tables and Knelson concentrators.

This report presents four processing options for the Tabuaço project evaluated during a Pre-Feasibility Study (PEA). Options A1/A2 and A3 focus on producing a scheelite concentrate via flotation, with Option A3 incorporating ore sorting to reduce plant feed tonnage. Options B1/B2 and B3 extend this path by including acid leaching of the concentrate to produce high purity tungsten oxide (WO3). Option B3 also utilizes ore sorting. The proposed acid-based processing path is estimated to be less capital and operating cost intensive than the traditional ammonium paratungstate (APT) processing path.

This NI 43-101 Technical Report presents a Feasibility Study for the Santa Rosa Gold Project, operated by Red Eagle Mining Corporation. The document focuses heavily on the recovery methods and process design required to extract gold from the ore body. Section 17 outlines the comprehensive recovery methods, ranging from run-of-mine handling to tailings disposal.

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.

This Pre-Feasibility Study (PEA) outlines the conceptual recovery methods for the Bégin-Lamarche Phosphate Property. The process flowsheet is designed to produce high-grade apatite concentrate suitable for purified phosphoric acid and magnetite concentrate. The nominal processing capacity is 12,000 tpd, ramping up to 20,800 tpd by the end of mine life. The ore is processed via open pit mining, followed by crushing, grinding, magnetic separation, and flotation.

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.
