·We verify that the maximum capacity of the scale is not exceeded.
·We verify the scale calibrations.
·We check seals and/or sealing of drums, Big-Bags, Maritime containers...
WAREHOUSE SUPERVISION AND BULK CARGOES INSPECTION
We can mention the following:
·Weighing, reception and stowage.
·Verification of the storage conditions.
·Prevention of mixing with other cargoes.
·Continuous information.
·Contamination prevention.
·Periodic visits.
·Cargo conditioning for loading operations.
LOADING AND DISCHARGING SUPERVISION
We offer the best loading or discharging procedures for avoid losses of material during operations, preventing pollution and avoiding that bad weather conditions affect the quality of the cargoes:
·We verify the loading/discharging equipments to ensure a correct handling of the cargo.
·Supervision of the cleaning and condition of the vessel's holds.
·Cargo condition inspection evidencing and/or avoiding contamination.
·We supervise the Draft Survey Calculation with special attention on:
-Age and general condition of the vessel.
-Information and hydrostatic calculations.
-Confirmation of the draft marks.
-Ballast tanks condition.
·We verify the weighing facilities.
·We supervise loading and discharging operations of the trucks, checking that they are in good condition for transport each different cargoes.
SAMPLING AND SAMPLE PREPARATION
We propose the most appropiate sampling procedure for each type of cargo, supervising it or performing it as required.
·Sample processing.
-We check that sample preparation area is clean and in good condition to process it.
-Correct and careful handling.
-We supervise or perform a correct packaging, sealing and identification of the sample.
-Preparation of final quality samples for chemical analysis.
·Sample distribution.
-We distribute the required samples by the client according to their instructions using the most effective way.
-We keep in reserve the samples for possible umpire analysis.
MOISTURE AND GRANULOMETRIC CURVE DETERMINATION
· Moisture determination.
-Correct identification and tare of the trays.
-We verify the scale and test all the weights.
-We supervise all the drying process in the drying ovens.
-Each sample is dried till constan weight is achieve and its weighed properly.
-We check all the calculations.
-All this tests are carried out in duplicate.
· Granulometric curve determination.
-We guarantee that ther is no alteration in the granulometry due a bad handling.
-We ensure that the increments taken are totally representative.
Chemical Analysis
The Alex Stewart International Laboratory Network provides a wide range of accurate and independent analytical services for base metals, precious metals, ores and concentrates, ferroaloys, metal recycling and electronic scrap, coal and coke, geochemical and exploration mining, metallurgy and environment.
The analysis are carried out combining the classical wet/dry digestion techniques with modern state of the art laboratory instrumentation such as ICP, XRF, IRC and the most modern titration systems.
Our main advantage is that we directly perform the whole process, from the first technical consultancy, inspection and/or sampling and final quality sample preparation, so the samples are in the necessary condition to carry out a chemical laboratory analysis.
