Recently, processed foods have become an important part of human eating habits. However, several processing techniques, such as dehulling and roasting, are applied to raw foods. Roasting is a thermal process that depends on temperature time improves the extraction yield oil by generating pores in oilseed cell walls. Sesame (Sesamum indicum L.) annual plant belonging Pedaliaceae considered be on...

Tantalum, niobium, and their oxides are important precursor materials, essential for high-temperature alloys electronic devices. The primary hydrometallurgical extraction technique to extract tantalum niobium from minerals involves hydrofluoric acid (HF) digestion of the concentrates, followed by solvent as an oxide separation purification step. Solvent extraction, on other hand, releases organ...

BACKGROUND The paper looks at the levels of canolol, tocopherols and antioxidant activity in cold-pressed and hot-pressed rapeseed oils produced from seeds of various moisture levels (5%, 7.5%, and 10%). The paper also considers the effects of seed roasting on the levels of these compounds. METHODS The material used for the tests was rapeseed cv. Adrianna. The quality of the oils obtained is ...

A chlorination roasting-water leaching process to recover Li, Ni, Co, and Mn from spent Li-ion batteries is introduced in this paper. The key parameters were studied optimized, over 98% of 97% can be leached out under the most suitable condition 350 °C roasting temperature, 30 min time, a 2:1 mass ratio NH4Cl cathode powder. During process, first sublimated transformed into H3N···HCl(g) complex...

Rare Earth (RE) phosphors waste contains valuable rare elements (REEs), such as cerium, terbium, yttrium, and europium. In industry, the process of NaOH roasting followed by acid leaching is usually used to extract REEs from in China. Using this process, efficiencies cerium terbium are clearly lower than those other REEs, which results uneven extraction low total REE efficiency. The key reason ...
