Explosive hazards

High-order explosives are chemicals with a high rate of reaction. They include nitroglycerine, dynamite, C-4 (a common commercial and military explosive) and a mixture of ammonium nitrate and fuel oil. When a high-order explosive detonates, the chemicals are converted into gas at a very high temperature and pressure.

Which of the following processes are associated with comminution of ore

Which process is used for dressing of ore? The removal of unwanted earthly and siliceous impurities ( that is, gangue or matrix ) from the ore is called ore - dressing or concentration of ores and the process used to concentrate an ore is called the benefaction process. What are the processes associated in mineral processing? Unit operations.

Iron ore mining and dressing

Jun 21, 2018Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.

Mineral dressing (= Orebeneficiation)

Both 2,4,6-trinitrotoluene ( TNT) and 2,4,6-trinitrophenol ( picric acid, PA) can cause a significant fluorescence quenching of TPE-CP due to the electron transfer from TPE-CP to TNT or PA. Additional energy transfer makes PA more sensitive to TPE-CP than TNT in the fluorescence quenching detection.
