The majority of the plant should still be green, but with a bit of yellowish tinge, especially on the heads of the plant. To test crop stage, squeeze a random kernel between your fingers to see how soft it is. At the soft-dough stage you should get a white, soft paste-like substance coming out from the seeds.


Processing about 4–4.5 tonnes of nepheline ore yields 1 tonne of alumina, 9–11 tonnes of cement, 0.6–0.8 tonnes of soda ash, and 0.2–0.3 tonnes of potash. According to the grade of the bauxite ore, 2–3 tonnes of ore yield one tonne of alumina and about one tonne of red mud (dry weight). When designing an alumina plant, factors

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).


The answer to every "what do I do with this thing I don't need" is always to find a way to turn it into a gas or a liquid that can either be burned in a flare or evaporated in a clarifier. There is nothing you can't make in massive quantities later, do t store stuff you don't need.

Slag - Wikipedia

Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be …


Processing From Minerals In contrast to salar brine sources, extraction of lithium from spodumene, lepidolite, petalite, amblygonite, and eucryptite requires a wide range of processes. Because of the amount of energy consumption and materials required, lithium production from mining is a much more costly process than brine extraction, even ...


D. Sichen, in Fundamentals of Metallurgy, 2005 9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the …


The use of slag for the manufacture of both slag cement and Portland cement has assumed very large proportions both in U.S.A. and Europe—so much so that in the former country plants not well situated and equipped for cheaply making cement from clay and limestone are being forced to close down.

Slag cement is as old as iron-making itself. In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s. In the U.S., blends of slag and portland cements were introduced in 1896. Today, slag cement can account for 30% to 50% of the cement ...

Aluminium production process

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
