A Sampling System or Station is designed to collect a representative sample of a specific material that needs to be analyzed. The system must comply with both national and international standards, as well as operational requirements.
A proper system must be fully designed according to the specific conditions of the plant.
There are four types of systems:
-
Pulp Sampling System
-
Ore Sampling System
-
Concentrate Sampling System
-
Solution Sampling System
1. Pulp Sampling System
These are installed at pipe or launder discharges with the goal of capturing the entire flow of a stream. The configuration may consist of multiple sampling stages, depending on the flow rate and variability of the material.
Their main installation points in a plant are: Feed, Final Concentrate, and Tailings.
The design and supply capacity can reach up to 22,000 m³/hr.
2. Ore Sampling System
These systems are installed at conveyor belt discharges or at their transfer points. The configuration depends on the tonnage and material characteristics. They are designed to obtain samples for chemical and particle size analysis.
Main installation points include: plant feed, purchase control, among others.
Design and supply capacity can reach up to 10,000 TPH, and a particle size of up to 4 inches.
3. Concentrate Sampling System
These are installed at conveyor belt discharges or at transfer points. The configuration depends on the tonnage and material characteristics. They are designed to obtain samples for chemical and moisture analysis.
Main installation points include: filter discharges, dispatch, and material reception, such as shipping ports.
Design and supply capacity can reach up to 5,000 TPH, and moisture content up to 12%.
4. Solution Sampling System
These are installed directly on a solution line (pipeline). The configuration depends on the flow rate and customer requirements.
Main installation points include PLS lines and homogeneous solutions.
Design and supply capacity can reach up to Ø10” and with low PPM concentrations.
