High-pressure oxidative acid leaching of SFT was carried out to assess the effects of sulfuric acid concentration, oxygen partial pressure, reaction time, solid/liquid ratio, and temperature on the extraction of copper, cobalt, zinc, and iron. The dissolution of metals from the SFT sample increased with temperature and sulfuric acid concentration.

To reduce Ti-bearing blast furnace slag wastage, our group previously developed a metallurgical process in which Ti-bearing slag was produced using Na2CO3 instead of CaO. This process increased the TiO2 content—in the form of Na2Ti16O33 (40.93%) and CaTiO3 (42.77%)—of the slag from 22% to ~43%. In this report, a method …

Introduction. Geopolymer is a class of alkali aluminosilicates produced by reaction of solid aluminosilicate precursors with alkaline activator [1], and today, 'geopolymer' usually refers to a wide range of alkali-activated cements (AACs), including alkali-activated blast furnace slag (AAS), alkali-activated fly ash (AAFA), alkali-activated …

Unlike guinea pigs who were exposed to sulfuric acid without atropine pre-treatment, the atropine-treated animals had no signs of pulmonary injury, such as epithelial desquamation. It was concluded that pulmonary injury following sulfuric acid exposure may be due in part to mechanical forces generated during reflex-mediated bronchoconstriction.
The mass loss or weight change (in percent) can be calculated by the following equation: (1) mass loss, in percent = w i − w t w i × 100 %, where w i is the initial weight of a specimen after 28-day curing before immersion in the sulfuric acid solution (g) and w t is the weight of the specimen after immersion in the sulfuric acid solution (g ...

Hydrochloric acid solutions behave similarly to sulphuric acid mixtures. Because the action of hydrochloric acid on both oxide scale and base metal is exceedingly rapid, it must be used with extreme caution. Unlike sulphuric acid, however, hydrochloric acid produces ferric chloride which is a strong pitting agent. As the salt content builds
The preparation of cementitious materials by coal gasification coarse slag (CGCS) and sulfuric acid activator was proposed. ... In terms of salt activation, Yang et al. [21] studied the amount of sodium sulfate (SS) in the cement–eolian sand cemented filling material system and its activation effect. Under the action of SS, the consumption of ...

Firstly, orthogonal tests were conducted by selecting four levels under each of the five factors: modulus, alkali equivalent, water-binder ratio, lithium slag replacement, and binder-sand ratio. Based on the results of 16 sets of fluidity and setting time experiments in the orthogonal tests, the base ratio of lithium slag base geopolymer was ...

Sulfuric acid is, as we've explained, a highly dangerous product. However, it's a widely used chemical that you can find in manufacturing plants across the world, as well as in many cleaning products. Sulfuric acid can cause serious, long-term injuries when handled incorrectly, and in some cases can even cause death.
