The processing of potash ores by hot leaching with further crystallization of potash salt from saturated salt brines (halurgical method) began in XIX century in Strasburg. The primary methods of potash ore processing are flotation (mechanical method) and hot leaching (chemical method).

When the Moors conquered this part of Spain during the Middle Ages, the oxide ores had largely been exhausted.
get priceIron and Steel Manufacturing Industry Description and Practices Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufac-turing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is con-verted to steel in a basic oxygen furnace (BOF).

get priceThe process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel.

get priceThe HIsarna steelmaking process is a process of primary steelmaking in which iron ore is processed almost directly into steel. The process is based on a new type of blast furnace called a Cyclone Converter Furnace, which makes it possible to skip the process of manufacturing pig iron pellets, a necessary step in the basic oxygen steelmaking process.
get priceThe main goal for the processing of iron ore is to take the ore extracted during the mining effort, break the ore into usable units and then purify those units before the actual smelting begins. Doing so makes it easier to produce a higher grade of iron that in turn can be used to create materials for use in everything from manufacturing
