  • how to screen low grade gold stockpiles

    Process low-grade stockpiles earlier for pre-treating refractory gold, the main objective is to oxidise the pyrite and arsenopyrite to liberate gold. Initially, the target is refractory gold-bearing iron sulphides where currently pre-treatment is the only solution to recover sulphide mineral matrix, locked inside the gold.

  • Financial Modelling of Stockpiles in a Mining Project

    Average grade (H35) = available contained gold (H30 + H31) available ore mined (H24 + H25) The stockpile calculations are a critical component of a mining financial model Modelling stockpiles is a crucial component of a financial model in a mining project, because most likely mining companies are not able to mill all the ore that they mine.

  • Extracting from low grade ores Fruitful

    Many existing gold refractory operations have low-grade stockpiles that are waiting to be processed at the end of the mine life. By adding Rapid Oxidative Leach® (ROL®) pre-treatment to an existing operation, it can become viable to process these low-grade stockpiles earlier, rather than processing them at the end of the mine life. Reducing

  • Grab sampling for underground gold mine grade control

    GRAB SAMPLING FOR UNDERGROUND GOLD MINE GRADE CONTROL 99 Grab sampling was used at the Tarnagulla mine (Victoria, Australia).7,8 Studies undertaken in 1989 involved grab sampling from rail trucks to estimate the grade of two trial mining parcels of 250 t and 350 t respectively. Two 1 kg samples were taken out of each truck at the shaft station.

  • Ore Stockpiling Why are we doing this again?

    Apr 28, 2016· Possibly one or more grade stockpiles may be used, for example a low grade and a medium-low grade stockpile. Such stockpiles may not get processed for years, possibly until the mine is depleted or until the mined grades are lower than those in the stockpile. Such stockpiles can grow to enormous size if accumulated over many years.
