This week, we continue our series of posts on the topic of Blast Hole Sampling and Analysis in Ore Grade Control in Mining and today we are talking about IMA Engineering’s Methods, Equipment and Results for Blast Hole Sampling. This article and the attached white paper are the continuation of our previous article that you can read here.

Blast hole sampling and analysis in Ore Grade Control in Mining is a topic that we feel, hasn’t been covered enough. During the month of March 2021, we aim to bring some clarity on this topic and to present some solutions to the current challenges faced by mining companies all over the world.

When working with drill cuttings sampling analysis we noticed that the conventional samplers with riffle and cone type sample splitters that take physical samples from drill chip were not giving good enough representative samples. We thought that there has to be a better way - and came up with the Autosampler, our drill cuttings sampling device.

Waste rock removal in preconcentration has direct effect on energy consumption in crushing and grinding and chemicals in concentrator. In concentrator waste is separated and goes to tailings pond, however, preconcentration directly reduces the volume of the tailings.
