Formulation and use of Minimum Sample Mass Models for various ore forms and metallurgical products (SAG mill feed, drill core, ball mill feed, flotation concentrate, final tailings).
The rules of unbiassed sample extraction.
The Semivariogram to demarcate autocorrelated and independent time, plus other useful features such as the estimation of fundamental error of sample extraction.

Workshop #2 Training in the laboratory

Presented by CALA

September 9, 2024 Afternoon

Lab staff and management often find themselves thrust into the role of trainer, often with little or no experience in how to effectively train. Whether it is training new staff in everything they need to know, or training existing staff on new equipment or procedures, how we conduct the training has a direct impact on how well the trainees perform.

This half-day session will look at the importance of planning for the required outcomes, approaches to successful training, and how to assess whether your trainees are competent.
