The gold bearing ore from the open pit mine will be stored on the ROM in separate stockpiles of varying ore types (oxidation stages) and grades to facilitate blending of the feed into the crushing plant. The estimated maximum particle size of ore on the ROM pad will be 800 millimetres in any dimension.

Upgrading low grade gold ore stockpiles. Sensor-based automatic ore sorting technologies are used in the minerals industries to efficiently remove waste and sub-marginal grade material from crushed and screened run of mine (ROM) ore, producing a coarse (typically >10 mm) upgraded pre-concentrate at an early stage in the mineral processing circuit.

Apr 08, 2018 Boom conveyors usually are in the 30-60m (100-200 ft.) range. Blending is accomplished by layering, building separate stockpiles and reclaiming simultaneously, or, in the case of the slewing traveling stacker, by laying down windrows of alternating types of ore to build the stockpile. Upon reclaiming, the stockpile made of windrows blends ...

May 31, 2016 ROM (run of mine) gold ore is delivered in large haul trucks (190- and 300- ton capacity) to a series of stockpiles where it is segregated based on ore grade, fuel value, and carbonate content. A loader reclaims ore from the different stockpiles and loads it into smaller haul trucks (85-ton capacity) to create a uniform blend.
