Blast holes analyzed on-line in real time!
With the new version of the PDSA Sampler-Analyser, you can analyze the entire production bench before charging with explosives.
With this analysis, you can get accurate blasting and loading maps with benefits:
- less waste rock dilution and higher head grade
- better separation of acidic and clean waste rock in mine waste area
The technology proof of the new method was financed by EIT Raw Materials.
With the new method, you get representative samples and accurate analysis of the bench.
PDSA Sampler-Analyser in an IMA Sampling Van moves between drilled cones/piles. Samples can either be taken from the cones using the IMA Samples Belt and put directly to online analysis or they can be taken into buckets and poured into the PDSA Sample Hooper.
PDSA can analyze piles or cones quickly and in a representative way. Almost all chips are analyzed without splitting or sample handling and a bench can be completed during one shift.
This method is economical because it saves costs by requiring a minimum number of samples to be analyzed in the laboratory.
The method is also ecological, offering a sustainable future for the mining industry.
The PDSA Sampler analyzer can be effectively used at Ore Waste contact to avoid dilution. This leads to less waste rock to mill, less energy consumption, and fewer chemicals. Ore waste border is more accurate, the explosives are charged with more precision so there is less ore loss.
In the side rock areas, the PDSA can separate acidic (sulfide) from clean waste to avoid acidic drainage into nature.
The PDSA Sampler Analyser provides a semi-automatic operation as it is placed in a van that can move between rows of drilled holes.
Blast holes analyzed on-line in time! FASTER and REPRESENTATIVE ANALYSIS OF CONES PDSA Sampler-Analyzer in an IMA Sampling Van moves between drilled cones/piles. Samples from the cones can be directly taken with the IMA Sampler Belt into on-line analysis or sample buckets and poured into the PDSA sample Hopper.
When the IMA Sampler Belt is used, cuttings are shoveled onto the sampler belt, moving the chips into the PDSA Sample Hopper for analysis. Samples (5kg bucket) can also be poured into the PDSA Sample Hopper.
With this new method samples from the different parts of the hole can be analyzed separately, providing either a sectional or an average analysis of the hole.
Make it stand out
Whatever it is, the way you tell your story online can make all the difference.
The hole ID can be typed on the panel before analysis or its GPS coordinates can be used.
This method is fast, analyzing piles in 2-3 minutes and 20-30 holes in an hour. The hole bench is finished in a shift or two while drilling continues and is finalized.
What is IMA Engineering?
IMA Engineering has used on-line sensors for analyzing ore and waste rock in mining for over 25 years. Today IMA on-line sensors are used in various stages of the mining process including on-line analysis of drill cores, drill chips, ore, and waste in loader buckets, ROM ore analysis on conveyor belts and in bulk ore sorting, as well as slurry analysis in concentrators.
