JKL MPSC® Manual Spot Sampling Probe

Application: Manual Sampling of Mineral Slurries in Operating Metallurgical Circuits

1. General Description

The JKL MPSC® Submersible Manual Sampling Probe is a specialized device designed for spot collection of mineral slurry specimens in metallurgical processing operations. It is engineered for operational verification of flotation circuits, thickening systems, and hydraulic transport of concentrates and tailings.

Developed by JKL Mineral Dressing, this equipment provides a robust, precise, and safe solution for obtaining representative process samples at strategic sampling points, enabling effective monitoring and control of critical metallurgical variables such as:

• Slurry density
• Percent solids (% w/w)
• Particle size distribution (PSD)
• Metal grade and metallurgical content
• Circuit performance evaluation

SUBMERSIBLE PROBE

The probe functions as a point-verification sampling device, designed to ensure high sampling efficiency under demanding mining plant conditions.

2. Construction and Materials

The JKL MPSC® probe is entirely manufactured from high-grade materials selected for severe slurry service environments characterized by abrasion and chemical exposure.

• Structural arm: ASTM A304 stainless steel
• Sampling container (1 L bottle): AISI 316 stainless steel
• Mechanical components: Designed for operation in harsh metallurgical environments

The equipment consists of:

Spot sampling tool with 304 stainless steel tubular arm and 1-liter AISI 316 stainless steel collection vessel

This material configuration ensures:

✔ High chemical resistance to acidic and alkaline slurries
✔ Superior abrasion resistance against suspended solids
✔ Extended service life in concentrator plant environments

3. Functional Design

The JKL MPSC® model includes:

• Modular tubular arm (length configurable per project requirements)
• Dual manual actuation system
• 1-liter sampling bottle with hermetic sealing caps
• Upper sealing mechanism
• Lower controlled discharge system
• Ergonomic handle for safe operation

The functional design allows:

• Controlled immersion at the designated sampling location
• Full container filling under submerged conditions
• Hermetic sealing prior to extraction
• Direct discharge into an external container (standard bucket)

4. Operating Principle

1. The probe is vertically positioned at the designated sampling point.
2. It is submerged until the sampling bottle is fully immersed in slurry.
3. The upper actuation mechanism is engaged to seal the collected sample.
4. The probe is withdrawn from the slurry stream.
5. The specimen is discharged into an external container via the lower actuation system.

This operating sequence:

• Minimizes sample loss
• Reduced cross-contamination
• Prevents segregation during extraction
• Ensures safe and controlled handling

5. Typical Applications

• Manual sampling in flotation circuits
• Spot density and percent solids control
• Metallurgical verification of concentrates
• Tailings monitoring and control
• Validation of online process analyzers
• Metallurgical audits and process diagnostics
• Operations where installation of automatic sampling systems is not economically justified

6. Technical Advantages

✔ Portable and rapidly deployable equipment
✔ No electrical power supply required
✔ Easy disassembly and transport
✔ Minimal maintenance requirements
✔ High structural durability
✔ Heavy-duty design for plant service conditions
✔ Operable by one or two technicians
✔ Low capital investment compared to automatic sampling systems

8. Warranty and Technical Support

• Warranty: 12 months from commissioning or 18 months from shipment (whichever occurs first)
• Permanent local technical support
• National manufacturing with internationally certified components

9. Contribution to Metallurgical Control

The JKL MPSC® probe enables:

• Collection of homogeneous and representative samples
• Early detection of operational deviations
• Validation of automatic sampling systems
• Reduction of uncertainty in metallurgical mass balances
• Improved reliability in metallurgical accounting

It is an essential tool for concentrator plants requiring spot verification and continuous process quality control within flotation, thickening, and hydraulic slurry transport systems.
