With the continuous mining of iron, high-grade, easy-to-select ores are increasingly depleted, and more and more attention is paid to low-grade, high-impurity-containing, and difficult-to-smelt iron ore resources. Limonite is a common iron ore mineral that often contains high levels of phosphorus, which can compromise the quality of steel produced from it. Traditional beneficiation methods struggle to effectively remove phosphorus from limonite, resulting in substandard results during the steelmaking process. However, a new innovative approach has emerged specifically targeting phosphorus removal from limonite, with remarkable success.

This new method combines advanced technologies such as magnetic separation, gravity separation, flotation and leaching to target the removal of phosphorus in an efficient and environmentally friendly way. By selectively extracting phosphorus while leaving iron content unchanged, the beneficiation process ensures high-quality iron ore for steel production. The main purpose of beneficiation is to remove phosphorus and obtain high-grade limonite concentrate, in order to obtain high-grade limonite concentrate. Next, let’s learn about the phosphorus removal and beneficiation methods of limonite!
