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 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.
· 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.
· 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.
· For example, the environmental impacts of a metal are heavily dependent on ore grade, and so can vary significantly even within a single mine. It is not practical to include every material and energy input, so significant …
· Conversion of Chromium Ore Processing Residue to Chrome Steel Introduction Chromium played an important role in the industrial development of New Jersey from 1905 to 1971. During that period, chromate (Cr6+) was produced from chromite ore at three facilities in Hudson County, NJ. During the chromate extraction process, varying amounts of lime ...

· ) produced in the ore processing plant is known as yellowcake and usually contains between 60 and 85 per cent uranium by weight. Depending on its quality, the concentrate is sometimes further purified in a refinery near the mine before being shipped in metal containers to a conversion plant. 3.2.2 Conversion
· Tumas 3, representing approximately the first 15 years of ore feed for the Project. This work has been very successful and the Company believes that the PFS assumptions have been confirmed as prudently conservative and the DFS process design will be based on 98% beneficiation recovery, with between 50% and 60% mass rejection to a coarse tailing.
· No matter how sophisticated a model for prediction of important sustainability parameters, a number of assumptions must be made to yield the desired information. Some of these assumptions are well understood, and stated clearly in the description of the particular model used. However, in many cases, assumptions are not clearly stated, or sometimes not …
Modelling levels and their assumptions in minerals processing based on the feed stream components. The model is valid and can be extended outside the …
· The system boundaries using primary ore materials and production of a LIC module using recycled materials from an end-of-life LIC are shown in Figure 1 and Figure 2. The system boundary includes raw material extraction, electrode material production and cell build for the 48 V LIC module. Both system boundaries exclude the operational usage ...
· The following assumptions were used in the assessments of worker and public doses presented in Attachments 1.1 and 1.2: 1. Ore grade assumed to be 0.25% input and 1-2% output from the ablation process; ore grade in the post ablation …
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 …
• The ore transported from the mine will be processed in the processing plant built for the ilmenite project and a vanadium factory which will be built with the funds raised in the IPO. At this stage the processing plant will be expanded to service the needs of the mining operations (including a second phase crushing facility)
· processing capacity, mineral recovery and processing costs such has ore hardness. For consistency the Mining Dilution estimate and the resultant grade dilution should be adjusted by metallurgical algorithms. For example where magnetic separation is used the silica in the contaminant material will be eliminated by magnetic
· Raw ore allocation in mineral processing is crucial for improving the utilization ratio of nonrenewable raw mineral resources. Allocation of raw ore is a nonlinear, multiobjective programming problem. Such a problem is usually modeled under the assumption that the production process is stationary and the model parameters are deterministic. However, in …
