BS EN 13657 Aqua Regia Extraction of Ore Samples Testing
The BS EN 13657 standard provides a detailed method for the extraction and analysis of precious metals from ores using aqua regia. This technique is particularly useful in mining testing where accurate determination of precious metal content, such as gold, silver, platinum, palladium, and other noble metals, is required.
According to BS EN 13657, the extraction process involves dissolving ore samples with a mixture of hydrochloric acid (HCl) and nitric acid (HNO₃), commonly known as aqua regia. This method ensures that both metallic and non-metallic components are dissolved, allowing for an accurate determination of the elemental composition.
The test is conducted in a controlled environment to ensure consistent results. The ore samples must be prepared carefully by crushing them into a fine powder using a jaw crusher or similar equipment. The sample preparation process is critical as it directly influences the accuracy and reliability of the final analysis. Once the samples are finely ground, they are weighed precisely before undergoing extraction with aqua regia.
The dissolution process typically lasts for several hours at room temperature under controlled conditions. After dissolution, the solution is filtered to remove any insoluble material. The filtrate is then analyzed using various analytical techniques such as atomic absorption spectrophotometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS), or X-ray fluorescence (XRF) spectroscopy.
The BS EN 13657 method ensures that all precious metals are extracted efficiently, providing accurate and reliable results. This is essential for mining companies to make informed decisions regarding ore processing and potential commercialization of the extracted materials. The standard’s robustness makes it a preferred choice in the mining industry.
The BS EN 13657 method also allows for the detection of trace elements, which can be crucial for understanding the geological history of the ore deposit and its economic viability. Trace elements such as arsenic (As), antimony (Sb), tellurium (Te), and selenium (Se) are often analyzed alongside precious metals to provide a comprehensive overview of the ore’s composition.
In conclusion, BS EN 13657 is an indispensable tool for mining companies, enabling them to extract accurate data on precious metal content. This information is vital for optimizing extraction processes, enhancing environmental compliance, and ensuring product quality. The method's accuracy and reliability make it a preferred choice among quality managers, compliance officers, R&D engineers, and procurement professionals.
