Class Codes & Rates:

Code 1438 is applied to insureds engaged in the extraction of non-ferrous metal from ore or ore concentrates. This normally begins with the receiving and stockpiling of ore followed by crushing, washing and screening. There may be various steps of milling, concentration or amalgamation preparatory to the sintering of the ore. The sintering is undertaken in rotary kilns or other types of furnaces. This may be followed by crushing the sintered ore preparatory to the actual smelting or reduction process. The molten metal that results is then cast into ingots. In many cases, small amounts of impurities may be removed by further refining in a furnace. Modern technology involves refinements in the basic extraction of metals.
