Metals to be coated require pre-treatment to remove rust or scale, impurities and inorganic contaminants. In steel industries, pickling process generates a considerable quantity of Spent Pickle Liquor (SPL) containing the dissolved metal salts of iron, chromium, copper, nickel and zinc as well as residual free acid. The waste …
According to GlobalData, Indonesia is the world's sixth-largest producer of bauxite in 2023, with output up by 2% on 2022. Over the five years to 2022, production from Indonesia increased by a CAGR of 17% and is expected to rise by a CAGR of 0.98% between 2023 and 2027.
The fastest growing export markets for Limestone of Indonesia between 2021 and 2022 were Canada ($141k), Maldives ($9.58k), and Nigeria ($3.5k). Imports In 2022, Indonesia imported $19.4M in Limestone, becoming the 8th largest importer of Limestone in the world. At the same year, Limestone was the 676th most imported product in Indonesia.
Limestone is a source of lime (calcium oxide), which is used in steel manufacturing, mining, paper production, water treatment and purification, and plastic production. Lime also has major applications in the manufacture of glass and in agriculture.

3.2 Changes in Mineral Elements Composition. Based on the X-ray fluorimetry experiment, the variation characteristics of main mineral elements content in limestone after different temperatures heated are obtained, as shown in Fig. 2 and Table 2.The overall changes are shown by the eight plotted curves, in which there is a …
The treatment efficiency of AMD-FC is affected by pH, the iron concentration, and the chemical properties of the solution, and reaches a maximum when pH is 6.3 and the iron concentration is higher than 0.0036 mg/L. At present, the treatment process generates electricity with a maximum power density of 290 MW/m 2 .
The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 …
Due to its unique rock properties (e.g., porous nature, rough texture, and high calcium and magnesium content), limestone exhibits a high degree of bioreceptivity.

limestone quality is determined based on the desirable oxides of calcium, silica, aluminum, and iron i.e. CaO, SiO2, Al2O3, Fe2O3 [1]. Limestone also contains some undesirable oxides like MgO, SO3, K2O, Na2O, and P2O5, etc. The raw mix for the cement plan is dependent upon the quality of limestone mined at a specific period.
