Mineral Processing Circuit

This Updated Preliminary Economic Assessment outlines the recovery methods for the Bell Mountain Project deposits, including Spurr, Varga, Sphinx, and East Ridge. Based on surface proximity and preliminary metallurgical test work, valley leach is the anticipated recovery method. The mineralized material features a significant silver content with a 25:1 Ag:Au ratio in some areas.

The San Ramon project, developed by Red Eagle Mining Corporation in Colombia, outlines a proposed processing facility for an underground mining operation. The design focuses on a Carbon-in-Leach (CIL) circuit capable of processing 1,000 tonnes per day of gold-bearing material. The facility includes primary and secondary crushing, ball-mill grinding, agitated leaching, and precious-metal recovery via electrowinning and smelting to produce a gold doré product.

The 2016 Preliminary Feasibility Study for the Azatek deposit outlines two processing approaches due to the complex mineral composition of the ore. The preferred method involves recovery of all components via bulk gold-bearing concentrates using gravity-flotation or direct bulk flotation, rather than selective processing circuits. The ore is characterized as gold-sulphide, polymetallic, or lead-antimonic, containing gold, silver, lead, antimony, and zinc.

The Charley Creek Rare Earth Project, proposed by Pancontinental Uranium Corporation, outlines a comprehensive recovery method for an alluvial deposit carrying heavy minerals. The mine site processing involves two wet plants and one dry plant designed to produce a REO concentrate grading around 40% TREOs. The wet plant utilizes scrubbing, hydrocycloning, and spiral gravity separation to upgrade the concentrate, while the dry plant employs electrostatic and magnetic separation to further refine the product. By-products include ilmenite and zircon concentrates.

This technical report outlines the recovery methods for the Tugaske Project located in Saskatchewan, Canada. The process plant is designed to produce 250,000 tonnes per year of saleable Muriate of Potash (MOP). The operation utilizes solution mining techniques, involving the injection of heated brine into underground sylvinite ore deposits to selectively dissolve potassium chloride (KCl). The resulting production brine is processed through a multi-stage crystallization circuit to recover KCl crystals.

This section outlines forward-looking information regarding handling and processing methods, plant design, and equipment selection for the CPP project. It details the current Wash Plant flowsheet performance and its suitability for future extraction ores, specifically North Dry Ridge and Husky1. The text reviews future beneficiation plant flowsheets, including modifications to process high MgO ores efficiently.
