This chapter details the recovery methods and process plant design for the Matupá Gold Project. The selected metallurgical process flow sheet is based on a robust route extensively adopted in the gold industry, featuring a primary crushing circuit followed by a single-stage SAG mill in a closed configuration with hydrocyclones. The process was optimized through third campaign testing, which confirmed that a gravity concentration and leaching process alternative offered higher metallurgical performance compared to direct leaching. The design criteria include a nominal processing rate of 3,562 tpd with specific availability targets for crushing, grinding, and filtration circuits.

The 2016 Summary Technical Report Update outlines the recovery methods for the Pine Point Mine Development Project, building upon the 2014 TAM operating plan. The project involves mining one underground and nine open pit deposits, utilizing a centralized Dense Media Separation (DMS) pre-concentration process followed by grinding and flotation at the R-190 concentrator site. The metallurgical program indicates that standard zinc and lead flotation preceded by DMS will yield excellent recoveries above 90 percent.

The Cusi concentrator is located in the outskirts of Cuauhtémoc City, approximately 50 km by road from the Cusi operations. The facility processes mineralized material delivered by dump trucks, each hauling approximately 20 tonnes of material. In 2019, the concentrator received 285,236 tonnes of mineralized material. Production volumes in 2020 were lower, with 117,320 tonnes delivered in the first eight months of the year.

This section of the NI 43-101 Technical Report details the recovery methods employed at the Topia Mine metallurgical plant. The process flow begins with coarse ore segregation into six bins, followed by primary crushing using a 15” x 24” jaw crusher and screening via a 6’ x 12’ vibratory screen. Oversize material is secondary crushed before entering a fine ore bin.

This technical report details the recovery methods for the Kitumba Copper Project, focusing on an optimized process flowsheet designed to process 3 Mtpa of ore. The primary objective was to increase copper recovery from 76% to over 90% while managing capital and operating costs. The revised flowsheet incorporates a pressure oxidation (POX) leaching step for the flotation concentrate, replacing the previous atmospheric leaching approach which yielded lower recovery.

The Greenhills Coal Operations (GHO) process plant utilizes conventional equipment and a conventional process flowsheet based on testwork results and industry standard practices. The primary operation involves separation by gravity for coarser particles, leveraging the difference in specific gravity between coal and rock. Mechanical means such as vibrating screens, cyclones, and spirals assist in this gravity separation to achieve desired specifications. Flotation is employed to recover fine coal particles, ensuring maximum recovery of clean coal from the raw feed.

This technical report details the recovery methods and processing infrastructure for the coal resources held by Wilson Creek Energy, LLC in the Northern Appalachian region of the USA. The report covers four primary mining sites: the Casselman underground mine, the Ankeny surface mine, the Acosta Deep underground mine, and the Hamer mine. Production from these sites requires beneficiation at a coal preparation plant to meet metallurgical coal market standards.
