  • Continuous Analyzer Integrated Data Validation
    Continuous Analyzer Integrated Data Validation

    Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.

The CNSolution 9310 analyzer is used in precious metal processing to measure and control cyanide used in the hydrometallurgical leaching of gold and silver from the ore.

Color, Turbidity And Philosophy Color, Turbidity And Philosophy

When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.

Pilot Testing Potassium Sulfate Crystallization Pilot Testing Potassium Sulfate Crystallization

ICP’s Ochoa Mine Project is projected to produce approximately 714,000 tons per year of SOP (K2SO4) from polyhalite ore for greater than fifty years as concluded in a feasibility study.

Mazzei Degas Separators Selected For Wichita Aquifer Project Mazzei Degas Separators Selected For Wichita Aquifer Project

A key component of the water supply plan for the City of Wichita, Kansas, was recharging the large aquifer that lies under the region with water from the Little Arkansas River. The river basin contains substantial farming operations which, during rain events, spike the river water with the commonly used herbicide Atrazine. Atrazine concentrations in the river frequently rose forcing the city to shutdown the bank filtration system. Advanced oxidation process (AOP) was selected to remove the herbicide. The AOP reactor’s design limited the amount of hydraulic backpressure it could tolerate. Consequently, Mazzei was challenged by the project’s design team to remove the entrained gas bubbles that remained from the prior oxidation treatment at a “not to exceed” hydrostatic backpressure of 19 feet.
