Fairness, integrity, and efficient detection of precious metal content
Analytical testing is important to determine the content of precious metals in process waste. Waste materials containing precious metals include spent catalysts, concentrates, ashes, powders and pastes, solutions and other materials with inconsistent shapes and uneven contents. Even small analytical errors in the precious metal content can lead to errors in the estimated value of precious metal scrap. Hirasawa Precious Metals' unique homogenized sampling and refining technology can recover precious metals efficiently, accurately and in an environmentally friendly manner. We can efficiently detect precious metal scrap in any form. We have our own laboratory for testing, and we can also entrust a third-party authoritative laboratory for testing.
