Ton (Assay) (UK) [AT (UK)]

The assay ton (UK) is a traditional British unit of weight used mainly in the mining industry for assaying ores. It is specifically designed to standardize the quantity of ore tested to determine its precious metal content.

One UK assay ton is equal to 28 pounds (about 12.7 kilograms). This is different from the British long ton (2,240 pounds) and allows for consistent sampling in metallurgical testing.

The assay ton (UK) provides a practical and uniform measurement for assessing the value of mineral deposits, especially in the context of gold and silver extraction.
