What is the RED Model of Critical Thinking? - Air University

assumptions which may not necessarily be warranted ; being able to identify these is a key aspect of critical thinking. An assumption question typically involves a statement and a number of assumptions. Your job is to identify whether an assumption has been made or not, and you will have a choice of two answers: yes or no.

Ore Reserve Estimation Method

 · Ore-reserve estimates are based upon the results of exploration and development and analyses of the samples derived therefrom. Unless a deposit is fully developed (and even then to a lesser degree), certain assumptions have to be made regarding the continuity and grade of ore between exposed faces or drill holes that have been sampled.

Theoretical Minimum Energies To Produce Steel

 · Fe) and ore ( Fe 2O 3) are much lower than consumed in practice, as are the theoretical minimum energies to roll the steel into its final shape. This study presents the absolute minimum energy required to produce steel from ore and mixtures of scrap and scrap alternatives, clearly defining the necessary assumptions involved.

Cut-off grade estimation - QueensMineDesignWiki

 · In the case of multiple processing options, cut-off grade is used to determine which process or destination the ore will be sent to, by using the following equation: Where U1 is the utility of sending ore to process 1, and U2 is the utility of sending ore to process 2. Utility is defined as the value (economic or otherwise) of selecting a process.

nickel processing - Extraction and refining | Britannica

The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production. The specific processes taken depend on …
