Smelting and Roasting Ores to recover gold, silver and

However, this "burning" or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state, allowing the values to be extracted. Exact temperatures used in roasting vary, and excessive temperatures can cause problems, including melting the sulfides before they can oxidize. Over the years, a number of small scale miners have sought to treat small lots

Steel production & environmental impact

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon
