Some of our challenges, solutions and outcomes!

Ferrochrome - High Risk. High Rewards.

November 20 2018 By CoalMin

In 2017 we were approached by a client in the Ferrochrome mining business with a challenge to initiate the production of a non-saleable (low grade-35 to 40 % Cr, 15 to 25 % slag content) PAC product.

The Solution: The outcome lay in a build, own, operate and manage (BOOM) solution. This was a modular solution and entailed CoalMin-owned technologies.

The outcome: Our client was delighted with the outcome which, within a period of just four months, reduced the slag content from 97% in the feed, to a slag content of 2.5 % in the final product! Once again our unique, patented technologies had provided a bespoke solution to this client's specific problem.


Foundry Sand Mastered.

November 19 2018 By Paola Pasteris

Our valued chrome mine clients approached CoalMin earlier in 2018  to assist in increasing their poor Foundry Sand output - (2 200 tons per month)

The solution: After conducting a feasibility study, CoalMin were able to ascertain that the solution lay in the possibility of increased Foundry Sand Production. The aim was to produce +10 000 tons per month.

The outcome: CoalMin met the mandate through providing a solution which included:

• Design

• Installation

• Commissioning and optimisation

• Training of staff and extended operation.

This was all achieved through the core competence of our staff and partners in just one month for the feasibility study and eight months for design, installation, commissioning, optimisation and the training of staff.


New Potential, New Product, Diversify the Market.

November 19 2018 By CoalMin

In 2017, the challenge for one of our premier clients mining chrome ore was that they were not maximising their potential - only producing metallurgical grade product as opposed to chemical grade product.

The solution: To design a 8 000 tons per month chemical grade plant.

The outcome: CoalMin provided a detailed design of a chemical grade plant which included:

• Plant mass balance and equipment sizing

• Signed off process flow diagrams and a piping and instrumentation diagram

• Construction layout

The time taken to complete the feasibility study was just one month. Because of our extremely competent staff and our commitment to excellence, CoalMin was able to provide complete designs in the next two months  - a quick but perfect solution for the client.


Zero to 100 000 tons in 1 month!

November 20 2018 By CoalMin

The challenge: In 2016, one of the coal mining exponents was faced with the challenge of not being able to supply coal for a seasonal market.

The solution: The only solution was for the company to produce what was needed to meet the fluctuating demands of a variety of products.

The outcome : Applying our skills and technologies, CoalMin not only skilfully managed to produce 300kt of required product in one month, but surpassed the client's expectations by doing so at a extremely low operating cost!
