PRECONCENTRATION AND ORE SORTING
believes it has a differentiated offering for the mining sector; an offering developed with these“ modifying factors” front of mind that has complementary solutions for bulk material on belts and in plant slurries.
The Thermo Scientific™ CB Omni™ Agile Online Elemental Cross-Belt Analyzer is designed for high throughput, bulk ore applications where decisions are made at and quantify the desired elements at very low grades with greater precision.
“ Because calibration is largely completed before shipment, on-belt deployment is typically limited to brief static checks and optional dynamic calibrations using known standards spanning the elemental ranges of the mine’ s own ore( no belt cuts needed), avoiding lengthy online campaigns and
• Belt loading and capacity( metres / second and tonnes / metre)
“ The net result is a variety of SDUs are possible depending on the chosen matrix of deployments selected above,” Rutter says.
He also outlined some of the key challenges for determining the best solution for a BOS opportunity, saying it needs to account for:
• Downtime on a conveyor for installation;
• Additional downtime or loss of production for any required“ online” calibration;
• Active diversion / intervention versus online process control solutions;
• Reject stream diversion capability or capital expenditure requirement;
• Reject stream haulage / removal cost and / or capital expenditure;
• Possible reject stream destination( eg waste dump or ROM leach); and
• Value proposition driven by increased grade, enhanced throughput capability and / or ability of processing facility to react to grade or information supplied.
This is where Thermo Fisher Scientific
The CB Omni Agile Online Elemental Cross-Belt Analyzer uniformly and precisely measures a wide range of industrially relevant elements, for entire raw material process streams, according to Thermo Fisher Scientific
variable scales of measurements from as low as tens of tonnes at a time.
The company provides the option of using either neutron sources – up to 78 ug of Californium 252 or an electronic neutron generator – and is combined with an option of 1 to 4 high volume Nal detectors, it says. The net effect is, the company says, a much higher saturation of neutrons to measure minimising downtime,” the company says.
The CB Omni allows short integration times – effectively pods of ore on the conveyor or sensor diversion units( SDUs) – and high analytical precision across a wide elemental range, including the light elements that cannot be measured by XRF, Thermo Fisher claims.
Rutter added:“ Because the CB Omni is
