Run-Of-Mine Ore Samplers

Accurate and precise knowledge of mineral values in ores delivers from a shaft or opencast operation to a metallurgical plant is a necessary control in efficient operation of a mine. With recent advances in this need can now effectively be addressed by Multotec's ROM sample stations. Recommendations are made on how much sample material to take and at what frequencies. Further advice on how to take it and the subsequent processing of sample is also provided.

Specifications

Copper, gold, platinum, nickel, lead, zinc, silver, etc. mineral ore applications.
Sample from 7000tph moving conveyors traveling up to 4m/s or more.
Maximum material feed size: 400-450mm.
Crusher reduction ratios of up to 10:1 for primary, secondary an/ or tertiary steps as required.
Final product size: 95% - 5mm (3mm minimum).
Sample collection: up to 20 container table indexer or carousel.

General

Ore mineralisation assessed before recommending a sampling regime.
Sufficient sample increment mass to be collected for statistically acceptable precision.
Ore grade variability data can be analysed for costumers.
Sampling frequencies recommended for each mineral and application.
Reliability of measurement os provided and is an important as the value itself.
Custom with ISO, JIS or other applicable sampling standards.

Benefits

Mining operations no longer reliant or reports process plant mineral values.
Long delays in the sampling and analysis of processed mineral overcome.
False mineral value reporting due to lock-up in metallurgical value reporting due to also avoided e.g. mills, thickeners, etc.
Verify that mine plan objectives are accomplished in day-to-day operations.
Provides a measure of delivered ore grades which need reconciled with metallurgical operations.
Assists in maintaining overall operational performance in terms of mine/shaft viability and efficiency.
Avoid stop-belt sampling with its costly labour requirements, tedious procedure, unproductive conveyor downtime and associated safety risks.
