Training

Define sampling objectives (chemical composition, moisture, etc.) and their purpose (process control, metallurgical balance, and others).
Design the critical stages of the sampling process (from sampling to subsampling and chemical analysis).
Evaluation of sampling errors according to short-term heterogeneity (EF, ESG, ED, EE, EP, EW, EN) and long-term heterogeneity (HFE2, HFE3).
Mineral heterogeneity test and determination of fundamental error variance.
Nomogram for determining the minimum sample weights required per stage.
Variography-semivariogram of the minimum sample weights required per stage. Evaluation and determination of sources of error generated in the plant.
Definition of sampling protocols, the type of sampling to be used (random, systematic, stratified).
