The ore powder contains 65% iron, corresponding to the content in the ore powder: 65%/72.41%= 89.77%; The rest impurities can be regarded as chronological gangue. The specific gravity of iron ore powder is about 5. 15, and the corresponding specific gravity is 2.65. (Iron content: 56 * 3/(56 * 3+16 * 4) =168/232 = 72.445438+0%)

Therefore, the corresponding specific gravity of mineral powder is: 89.77% * 5.15+2.65 * (100%-89.77%) = 4.62+0.27 = 4.89 (true specific gravity/density).

Extended data

Iron ore powder is made of iron ore (ore containing iron elements or iron compounds) through beneficiation, crushing, sorting and grinding. The types of iron ore powder are mainly divided into magnetite powder, hematite powder and limonite powder.

Silicate mineral powder of siderite and iron sulfide. Iron ore powder is the main raw material of iron and steel industry, which is often used in metallurgical industry, construction industry, shipbuilding industry, machinery industry, aircraft manufacturing and other industries with large steel consumption. Imported iron ore powder has a high taste, also called iron concentrate powder, which can only enter the blast furnace after sintering or pelletizing.
