Recovering Y and Eu from waste phosphors using chlorination roasting followed by a water leaching process was investigated in this study. Firstly, by chlorination roasting and water leaching, Y and Eu elements present in waste phosphors were efficiently extracted into a leach solution. Secondly, the majority of the impurities in the solution can be removed by adjusting the pH to 4.5 using a Na2...

The roasting of sulphide ores and concentrates is often the first step in the production of metals or chemicals. In many processes, the production of sulphuric acid is viewed as a by-product, while in some plants production is an important economic factor. Regardless of the purpose, a pyrite roasting plant consists of mainly three plant sections: roasting, gas cleaning and sulphuric acid. With ...

In traditional Chinese medicine (TCM), licorice is usually processed with honey and traditionally used in decoction form. However, the influence of honey-roasting on the main pharmacological activities and the water-soluble active constituents of licorice has not been reported. The aim of the present study is to determine whether honey-roasting can modify the main pharmacological activities and...

Carbothermic reduction-roasting tests of NCM (nickel, cobalt, and manganese) cathode active materials with carbon sources such as activated graphite followed by sulfuric acid leaching were performed to investigate the effects roasting temperature, molar mixing ratio sources, type materials. When virgin NCM622 roasted carbon, peaks Ni Co metals observed in XRD data. The efficiencies Li, Ni, Co, ...

Coffee roasting affects the taste, color, and aroma of coffee. The Maillard reaction, a major reaction during the roasting process, produces melanoidin, which affects the overall antioxidant capacity and anti-inflammatory effects of coffee. In this experiment, coffee roasting was divided into four degrees: Light, Medium, City, and French. To examine the in vivo antioxidant and anti-inflammatory...

In this study, studies were carried out to take into solution the element rubidium (Rb), which is in complex ore structure of Na + K feldspar, pyroxene and alumina silicate, an environmentally sensitive manner with high efficiency. Malatya - Kuluncak was used study. first stage roasting method tried obtain chloride (RbCl) or sulphate (Rb2SO4) structures, are water-soluble forms sodium-potassium...
