Sampling and Analysis Solutions for Mine Grade Control

IMA Engineering

Poor sampling results in substandard grade control, which causes problems when estimates differ from reality; a situation no mine worker wants to be in.

Innovative Mineral Analysers Engineering (IMA) has created a new representative sampling technology to enhance the profit line of mining businesses.

Innovative mineral analysis technology

IMA is an innovator of mining technologies and renowned for its geochemical analysers.

As the company has been working closely with customers for years, it has gained an insight into the real needs of the mining industry. And, as its name states, progress and development are at the forefront of IMA's values, encouraging customers to take the next step in mining technology.

Accurate sampling and grade control for mine planning

If grade control samples are incorrect and produced slowly it has a lasting effect on mine site planning.

To combat this, IMA Engineering has developed a new sampling technology and online solution to gain both representative samples from drill cuttings and instant XRF analysis of the samples.

The research project aimed to produce data from samples to enable more accurate mine planning and grade control. Representative physical samples together with frequent and fast online analysis have proven to be the keys for success.

IMA Engineering's new On-line Mine solution is now fully integrated on drill rigs and has already yielded positive results.

On-line Mine is a combination of several innovations, including but not limited to the following IMA Engineering technologies:

  • Sampler-Analyzer-Technology (SAT)
  • Analyze-While-Drilling concept (AWD)
  • Blast hole sampler-analyzer technologies (used in Atlas Copco OREalyzer / BSA)
  • On-line Drill Core Analysis technologies (used in Mine On-Line Service Scanmobile)
  • Fast Conveyor Analysis technologies (FCA by IMA Engineering)

Automated mine data collation and analysis

The new On-line Mine by IMA Engineering automatically combines various technologies into a complete, cost-effective solution.

Automated data from AWD and elemental analysis is collected into an xml file, which is sent to the mine database, for example Acquire, for grade control planning. Frequent analysis is used in order to produce the most accurate model of the blast bench.

On-Line Mine makes fast 3D models of the blast bench possible; a solution requested by many IMA customers.

The technology allows mine geologists to combine exploration data with the new, more dense MWD and AWD data in a modern database (Acquire) to:

  • Reduce waste rock dilution
  • Detect and estimate possible ore losses
  • Help prevent sulphides in the waste rock
  • Enhance the motivation of the workforce

The result is significant increase in ore value and mine profit.

Combined drill and sampler technology for efficient mining

IMA and Atlas Copco, the world's leading drill technology company, decided to combine their special expertise to make the innovative mining product of the decade.

OREalyzer is a new, integrated drill with a sampler / analyser that combines drilling, measuring, sampling and online XRF elemental analysis to produce both representative samples and an xml - data package, with information never seen before.

OREalyzer is now available in the global mining market via Atlas Copco.

Customised online mine solutions

IMA Engineering always aims to achieve better results for customers and continually develops new technologies with the one key aim of making mining more profitable.

IMA's solutions improve the profitability and ecological elements of projects.

IMA believes that the best outcomes are achieved when the company works closely with its customers. To ensure the most suitable solution is found, contact IMA to discuss your requirements and start developing your unique solution.
