Mineral Reserves Mineral Resources and Estimation

The goal of the exploration program is to proof up resources and reserves and to estimate the value of what is being found. In short to answer the question Can we make money from this pile of rocks or not Some background to this question of resources and reserves. In 1969 the Vietnam War was in full swing and the demand for nickel was soaring.

Nonparametric density estimation of bubble size

The mineral separation efficiency of flotation process depends very much on the surface properties of feed ore and addition of chemical reagents. Machine vision based analysis of froth appearance is considered as an indication of flotation performance. Bubble structure obtained by watershed segmentation scheme is used to determine the amount of reagent. To explore bubble size distribution

Evaluation of Acid Digestion Procedures to Estimate

In minerals analyses the digestion process is the limiting factor as to how much time the entire procedure takes and also concerns the efficiency of recovering the actual amount of mineral present in the sample (McCarthy and Ellis 1991). Considering that the interactions of minerals with organic matrices may vary depending on the analyzed

Improving assurance for Mineral Resource and Ore Reserve

For example some errors concern basic data verification and data preparation processes rather than somewhat more subjective choices about estimation-related parameters. Such issues highlight the lack of experience of the people tasked with the estimation and the lack of adequate internal peer review to identify such issues early.

Mineral Explorationan overview ScienceDirect Topics

Future ore bodies will probably be more costly to find mine and process than those in operation and production now because most of them will either be of lower grade or found at greater depths. The chances of a mineral occurrence being developed as a mine are low (may be 1 in 1000). Lesser number of identified resources does not imply low
