Extractive metallurgy - Wikipedia

Extractive metallurgy. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct use as a finished product, but more often in a form that requires further working to achieve...

Copper Smelting Chemistry Tutorial - AUS-e-TUTE

Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis (electrowinning) for low grade ores, or by the carbon reduction method of smelting for higher grade ...

Nickel: smelting, producing-Metalpedia

Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction. In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted.

STATE OF THE DIRECT REDUCTION AND REDUCTION .

product is referred to as direct reduced iron. The processes that produce molten metal, similar to blast furnace liquid metal, directly from ore are referred to as direct smelting processes. In some of the processes the objective is to produce liquid steel directly from ore and these processes are classified asdirect steelmaking processes.

HIsmelt | Industrial Efficiency Technology & Measures

Hismelt is a direct smelting process for making iron straight from the ore. Fine iron ores and non-coking coals are injected directly into a molten iron bath, contained within a Smelt Reduction Vessel (SRV), to produce high quality molten pig iron.

DIRECT IRON SMELTING REDUCTION PROCESSES

furnace, and direct smelting-reduction processes and direct-reduced iron is produced by coal- or natural gas-based direct-reduced iron processes. Pig iron is produced by the solid and liquid state reduction of iron oxides to iron and the consequent smelting of the feed stocks. Figure 1. Schematic summary of the iron- and steelmaking routes.

The Optimization of Processes for Direct Smelting of Lead ...

Emerging direct lead smelting processes offer advantages over blast furnace smelting, such as elimination of the sintering step and the need for coke, utilization of the exothermic heat of the oxidation reactions during smelting, potential use of pure oxygen, and production of a so2-rich gas.
