The focus is on both green and brown field projects to enable the client to perform detailed and precise valuations (NPV) of projects. This is achieved through metallurgical test programmes, design of the process flowsheets and selection of technologies which is subsequently incorporated within a full financial business model that include all operational and capital costing based on geological, mineralogical and metallurgical analysis.

This process is to obtain core information of the ore or mineral type. The data information can be classified into three groups:

• Geological analysis

Material mass

Material volume

• Mineralogical analysis

Densiometric analysis (density of particles)

Sieve analysis (Size of particles)

Chemical analysis (XRF, ICP)

Mineralogical analysis (QEM, XRD)

• Metallurgical analysis

Size & shape (screening analysis)

Gravity (water based like MGS or spirals)

Density (medium based like DMS)

CoreMet has a very strong ability to define, develop, execute and report on any metallurgical test work of study programme. CoreMet believe to have our client involved from the start of the study to:

Define the test work scope

Test work proposal approval

Test work execution to generate needed information like mass splits, recoveries, grades

Technical report

Project schedule management

Project cost reconciliation

• Software programs (Mine Intellect)

To develop and manage metallurgical plant standards to improve metallurgical performance, mechanical utilisation and plant efficiencies.

• Plant quality assurance & control programs

To stabilise process control & product specifications.

• Plant commissioning or plant audits

To reach design capacities, maintain production throughputs and qualities and increase product recoveries.

• Mine value chain audit

Audits or assurance engagements provide our client or stakeholder with an overview regarding the metallurgical integration within the mining value chain to ensure optimal production through put and to unlock more potential product value for our client.

Through equipment performance testing and modelling CoreMet is able to understand of equipment performance and efficiencies. This creates opportunities for equipment optimisation in order to increase plant throughput. CoreMet is able to evaluate equipment such as:

Crushers

Grinding mills

Cyclones (water & DMS)

Screens

De-watering (thickeners & filters)

CoreMet offer our clients fit for purpose processing plants in commodities such as chrome, iron ore, coal, heavy minerals and the three Ts (tin, tungsten and tantalum). CoreMet also offer our client the option to de-risk the project to offer a full capital operational turnkey BOOM or BOOT contract option.
