The "ton assay" or "ton assay UK" typically refers to the assay ton, a unit of measurement used in the mining industry to express the amount of valuable material contained in a quantity of ore. This unit of measurement is used similarly in both the United States and the United Kingdom.
An assay ton is defined as 29.1667 grams (or approximately 1.04 ounces) of ore material. It is a standardized sample size used for analyzing the composition of ore and determining the percentage of valuable minerals or metals present within it.
Miners and metallurgists use assay tons to assess the quality and economic potential of ore deposits. By analyzing a sample equivalent to one assay ton, they can estimate the likely yield of valuable minerals from a larger quantity of ore.
So, "ton assay UK" refers to the assay ton measurement used in the United Kingdom, which is the same as the assay ton used in the United States and other mining contexts.
In the United Kingdom, a "hundredweight" (abbreviated as cwt) is a unit of weight or mass used in various industries and commerce. However, it's important to note that the UK hundredweight is different from the US hundredweight in terms of its value.
In the United Kingdom:
1 hundredweight (UK) = 112 pounds (lbs)
So, while the US hundredweight is equal to 100 pounds, the UK hundredweight is equal to 112 pounds. This difference in value is important to be aware of when dealing with weights and measurements, especially in international trade or when comparing British measurements to those used in the United States or other countries.
