What Is 14K Gold Alloy? | Our Pastimes

All gold sold in the U.S. must by law be stamped with the alloy designation. In North America, a karat designation system is used. Gold that is 14K is 14/24 parts gold to alloy, or 58.33 percent gold. Jewelry manufactured in Italy is assigned a three-digit number known as the "fineness" number. The fineness number assigned to 14K gold is 583.

Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The

Gold Metallurgy

The early mining of gold ore in Minnesota was carried on with the most primitive mind of tools. The pioneers used only such equipment as could be packed from Duluth through one hundred miles of forest to the first mines on the Vermilion Range and the operations were carried on with picks, shovels, hand drills and wheelbarrows, the ore being hoisted in buckets with a horse winch and carted in


Nature entices man into the adventure of metallurgy by an initial gift of an almost magic charm. Gold, the most attractive and precious of metals in every society, is also the easiest for primitive man to acquire. Gold is bright, incorruptible, malleable, and appears in pure form in the beds of streams.
