The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

Generally, the ore and the gangue are mined together—i.e., taken out of the host rock in a mass by either mechanical or manual means. Then the ore is separated from the gangue by various operations known collectively as mineral processing, or ore dressing.
2 Gravity methods of separation are used to treat a great variety of materials, ranging from heavy metal sulphides such as galena (sp. gr. 7.5) to coal (sp. gr. 1.3), at particle sizes in some ...
In the 1850's the gold-rush prospectors and adventurers overran the entire Mother Lode country. They soon found the gold placers of Tuolumne County, which became the richest in California. During 1850-70 this county was one of the leading gold producers in the State.

The document summarizes the key steps in the ore dressing (mineral processing) process. It describes four main steps: 1) Comminution which involves crushing and grinding ore to reduce particle size. 2) Sizing by screening to separate particles by size. 3) Concentration using methods like hydraulic washing, magnetic separation, froth flotation ...
A gold carbonaceous sulphide ore from California carrying free gold yielded a 93 per cent recovery into a concentrate at 14.4:1 to ratio of concentration after conditioning with 0.50 lb. per ton of reagent 645. In each case the ore was ground to about 70 per cent minus 200 mesh and conditioned at 22 per cent solids with the reagents as indicated.
There was Pikes Peak in Colorado, which yielded gold and silver in 1859, but perhaps the most significant discovery was that of the Comstock Lode in Nevada, which would turn out to be the largest silver strike ever in the U.S. The Gold Rush in California began in 1849 and at first was a small, personal endeavor.
