Sampling has been considered in the mineral processing domain, where sampling errors may have large economic consequences (Gy, 1988) and a theory of sampling (TOS) has been developed by Pierre Gy. This approach has been shown to be applicable to other domains (e.g., Minkkinen, 2004; Paakkunainen et al. 2007).
The public reporting of Mineral Resources and Ore Reserves (in Canada, Mineral Reserves) must comply with various International Codes.In these there is always a requirement for the data to be appropriate for use in the estimation of tonnes and grades. This means that the collection of data should accord with sampling theory and the samples must be systematically reduced in particle size and ...

While the deposit qualities for mineral raw materials are constantly decreasing, the challenges for sustainable raw material processing are increasing. This applies not only to the demand for minimizing the consumption of energy, water, and reagents, but also to the reduction of residual materials, especially fine and difficult-to-landfill materials. Sensor-based ore sorting can be used as a ...
Lesson 3.1: General Concepts of Exploration. You'll recall the goals of exploration from Lesson 2.1 of Module 2. From a successful prospecting effort, we believe that we have found an economic concentration of a mineral. In the exploration stage, we will want to define …
Sampling - Selecting a fractional but representative part of a mineral deposit for analysis. Sandstone - A sedimentary rock consisting of grains of sand cemented together. Scaling - The act of removing loose slabs of rock from the back and walls of an underground opening, usually done with a hand-held scaling bar or with a boom-mounted scaling ...
2.2 Perfectly ineffective mineral processing, sampling theory and loss of memory To compare different mineral processing, or similar mineral processing applied to a different ore, it is necessary to have an invariant reference whatever the treatment and/or the ore considered.
