The ratio of alumina to silica is what really determines the quality of bauxite ore. The best bauxite ores have the highest ratio of alumina to silica and the lowest quality bauxite, vice versa. As a general rule of thumb, processing the best bauxite generates about 2 tons of red mud per ton of alumina. As the percentage of silica increases so does the amount of red mud. At more than 10

01/11/2019· Fig. 2c shows lead leaching ratio as a function of temperature under constant conditions of 400 g/L CaCl 2, 5 g/L Fe 2+, pH 1.5, and 2 h leaching time. A linear increase in the lead extraction was observed. The lead leaching ratio was only 75.8 at 50 °C and increased to a maximum at 90 °C. Thus, 90 °C is the preferable temperature for maximizing the lead leaching ratio. Even at a
Depending on the nature of the ore relative ratio of ore or other material and leaching agent may be such that the leach slurry contains from about 0,454 to about 45,36 kg of active agent per ton source.
The life of mine strip ratio is 1.3:1 waste:ore and it is anticipated mining will reach the maximum rate of 83,000 tons per day in 2001 with the final expansion of the mining fleet.

Pretreatment of coal by devolatization at temperatures ranging from about 420.degree. C. to about 450.degree. C. for from about 10 minutes to about 30 minutes before leaching with molten caustic leads to a significant reduction in carbonate formation, greatly reducing the cost of cleaning coal on a per ton
The brine dissociates andbines through exchange of electrons delivered by the current into gaseous chlorine, dissolved caustic soda1 and hydrogen. By the nature of the chemical reaction, chlorine, caustic soda and hydrogen are always manufactured in a fixed ratio: 1.1 tonne of caustic and 0.03 tonne of hydrogen per tonne of chlorine.
