Iron is a common ferrous metal that has wide application in various fields, including metallurgy, chemical industry, and the manufacture of mechanical equipment [1,2].Hematite (α-Fe 2 O 3), an iron mineral that is widely distributed in nature, is an important raw material for iron smelting.It also has applications as a red pigment Bench Flotation experiments in duplicate were performed in a 3 L Barker flotation machine. Agitation time with starch depressant was 5 min. Conditioning time with the collector was 2 min. Stirring with reagents was conducted directly in the flotation cell, with a pulp density of 33 wt% and the pH was maintained at a value varying between 9.5 The effects of partially replacing amine collectors by a

Hematite is commonly upgraded in China using a reverse anionic flotation process with starch as depressant for hematite, Ca 2+ as activator and fatty acids as collector for quartz. The Anshan type of hematite is well known for its low grade, fine dissemination, difficulty in upgrading, and huge reserve in China.

In this study, the flotation kinetics and entrainment in quartz and hematite single-mineral flotation systems as a function of the solid concentration and particle size were investigated usingThe primary separation method of hematite from its gangue materials has generally been magnetic separation process since iron minerals are both ferromagnetic and paramagnetic . The depletion of high-grade iron ore necessitates an upgrade. Froth flotation has been proven to be one of the most suitable separation methods used to this end [3, 5, 6].The effects of partially replacing amine collectors by a
