The leaching-precipitation method is suitable for the high phosphorus iron ore with phosphorus content more than 0.3%. The high phosphorus iron ore is leached with an acid solution to dissolve the phosphorus, and then the phosphorus is precipitated by adding a precipitant. The precipitated phosphorus can be recovered and utilized.
The manganese minerals in the ore are mainly pyrolusite, pyrolusite, and manganese ore; the gangue is mainly silicate minerals, and there are also carbonate minerals; it is often accompanied by iron, phosphorus, nickel, cobalt, and other components. Different types of manganese oxide have different colors, including black, brown-black, and pink.
This page looks at the use of the blast furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. ... Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulfur reacts with it to form magnesium sulfide ...
The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of important …
In this paper, a process of pre-oxidation and magnetization roasting followed by low-intensity magnetic separation and acid leaching (OMLA) was developed to separate and recover iron from siderite ore with high-magnesium and high-manganese. The pre-oxidation of siderite ore was performed in a tube furnace at 800 °C for 45 min, improving the ...

Steelmaking slag contains considerable amount of manganese (Mn) and phosphorus (P), and recycling them is an important issue. Since Mn is an alloy added to enhance the steel quality, while P is a harmful impurity in the steel product, they need to be separated for recycling. We have already found the possibility of separating Mn and P from steelmaking slag …
Manganese ore smelting is reviewed in terms of processing parameters such as feed material particle sizes, energy input methods, heat transfer modes, smelting mechanisms, experimental findings on ...
phosphorus from high-phosphorus iron ore has been studied [9–13]. The removal of phosphorus from high-phosphorus manganese ore has also been inves-tigated [14–16]. However, most such research has involved hydrometallurgy. The pyrometallurgical approach to the removal of phosphorus from manganese-bearing products,
For this purpose, the removal of phosphorus compounds by vaporization directly from manganese ores using a plasma system was investigated in this study. For the removal of phosphorus, the …
The ammonia-ammonium carbonate leaching method was proposed for the removal of phosphorus and extracting manganese from high-phosphorus manganese ore, both effectively and environmentally.
Manganese oxide ore processing mainly adopted gravity separation, and manganese carbonate ore processing mainly adopted flotation and strong magnetic separation. ... Iron and manganese are difficult to separate by gravity separation, ... Manganese and iron, phosphorus or gangue are closely associated, and the embedded particle size is extremely ...
