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 "quarter" is a term commonly used in the context of weight or mass, especially in agricultural and trade settings. A "quarter" in the UK refers to a quarter of a hundredweight (cwt).
In the United Kingdom:
1 quarter (UK) = 28 pounds (lbs)
So, when you see "quarter" used in the context of weight or mass in the UK, it generally means 28 pounds. This term is frequently used in the sale and trade of agricultural products and livestock, where quantities are often expressed in multiples of quarters. It's important to note that the UK quarter is different from the US quarter, which is 25 pounds.
