Mineralogical

analysis and reporting on metalliferous ores, gold and PGM, industrial minerals, slags and contaminants.

Materials

analysis and reporting on rocks, aggregates, building stone, slate, concrete, render and mortar.

Mundic Property Search

Since 1991, Petrolab has completed thousands of concrete screening tests on properties throughout Cornwall. Search our database and and see if your property is one of those tested.

Sample Preparation

Preparation of petrographic thin sections from samples and specimens of rock, aggregate, concrete and other similar materials.

Why Petrolab?

Mineralogical analysis

  • Identification and quantification of valuable and gangue minerals in ores

New Paper: Automated Environmental Mineralogy

Following the recently attended Sustainable Minerals conference, and the feedback we received our paper on the use of automated mineralogy has now been published in Minerals Engineering. This work has been a three-way collaboration between SRK Consulting, Geochemic and ourselves. This paper represents the first exploration of our use of Zeiss Mineralogic with mine waste assessments with more planned in the coming months.

Mineralogic 101 – Making the most of Mineral Lists

In a previous post we discussed the analysis modes that are fundamental to the data collection on Zeiss Mineralogic. In this post we’ll explore some of the basics of Mineral lists and some of the pitfalls to watch out for. As with any automated mineralogy software there are some foundational aspects that need to be established for the sample before any Mineral List can be set-up. These things include telling the software how many samples there are in the SEM, where those samples are, and in the case of non-standard sections, how big the samples are. The beam then needs to be calibrated and brightness and contrast set at a value that is suitable for the sample being analysed. With these set-up and the analysis mode decided it is then possible to move on to defining the Mineral List. A well developed Mineral List is a necessary pre-requisite to any data collection and interpretation.
