Mineral Processing Circuit

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.

This section of the Preliminary Feasibility and Technical Report outlines the proposed recovery methods for the Grassy Mountain gold-silver deposit. The design features a conventional Carbon-in-Leach (CIL) plant with a nominal throughput of 750 short tons per day. The process integrates gravity concentration to recover free gold before leaching, utilizing a mobile crushing facility and a ball mill grinding circuit. The plant is designed to operate with two shifts per day, 365 days per year, with an overall plant availability of 91.3%.

This technical report outlines the recovery methods and process design for the Nyngan Scandium Project, located in Nyngan, New South Wales. The project involves the extraction of scandium from scandium-bearing laterite ore mined via open pit techniques. The ore is processed through a sequence of crushing, grinding, and high-pressure acid leaching to recover scandium oxide.

Duluth Metals’ August 2014 report designs one SAG and ball mill line, forecasts 93.4% total copper and 54.7% nickel recovery, and returns thickened tailings to disposal or mine paste plants.

This NI 43-101 Technical Report outlines the Preliminary Economic Assessment for the Salar de Diablillos Project in Salta Province, Argentina. The project focuses on the extraction of lithium brine and the production of lithium carbonate, boric acid, and sylvinite. The proposed recovery method utilizes a combination of solar evaporation steps, in-field brine treatment, and chemical processing.

i-80 Gold’s 2026 study moves Granite Creek away from the heap leach and CIL options on this page: no ore is processed at the mine, and refractory ore goes by highway truck to a third-party toll mill and then to the idled 2,268 t/d Lone Tree pressure oxidation plant.

This technical report outlines the recovery methods for the La Cumbre project, detailing a dual processing strategy designed to handle oxide, transitional, and primary sulfide ores. The oxide and transitional ore is processed via a heap leach circuit involving crushing, agglomeration, and cyanide leaching, followed by solution treatment using Merrill Crowe and Carbon in Column (CIC) processes. The primary sulfide ore undergoes a conventional milling and flotation circuit, followed by tank leaching and carbon adsorption to maximize recovery.
