The flotation machine is used for mineral processing. The ore slurry is doped, stirred, aerated, and mineralized through a preprocessor so that some of the mineral particles are selectively fixed on the bubbles; they float to the surface of the slurry and are scraped out to form products. It is retained in the slurry to separate minerals.
Ilmenite flocculation flotation can also be divided into selective flocculation flotation and hydrophobic flocculation flotation, mainly for ilmenite with fine particle size. The selective flocculation flotation method is to first condense one kind of mineral in the slurry containing two or more kinds of minerals and then gradually separate them.

Usually, coarse particles larger than 2nm are removed (heavy minerals are generally below 0.3mm). Wet gravity separation aims to minimize the loss of valuable minerals and obtain heavy mineral enrichment (coarse concentrate). The commonly used gravity separation equipment is a cone concentrator or a spiral washer.
The effect of flotation time on the process. The most suitable flotation time for various ores is determined through experimental research. The following conditions can result in shorter flotation times： The minerals have good floatability. The content of floating minerals is low. The ore-feeding particle size of flotation is appropriate.
The dry magnetic separator is used for sorting dry magnetic minerals, and is mainly used for selecting large-sized, coarse-grained ferromagnetic ores and fine-grained weak magnetic ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m.
