In order to improve the separating index of ilmenite to separate the concentrate by high intensity magnetic separation, the Heishan iron ore in Chengde did some work. Separate the sulfide ore out by flotation under the conditions of concentration by weight in feed 32%, consumption of xanthate 200g/t and 2# oil 40g/t. Use sulfate to adjust the pH of the low sulphur product of flotation, the mixture of EM351-2 and EM351-3 as foaming agent, after one roughinging and four fold concentrating, got the final titanium concentrate, the grade of which is 47.23%, and the recovery is 58.29%. During the procedure of roughing, the consumption of the reagent as follows: sulfate 2kg/t, EM351-3 1kg/t, EM351-2 900g/t. The consumption of sulfate during fourfold concentrating is 1kg/t. The index is more stable when the concentration in feed is 18%~26% during flotation. The index is stable during the continuous 26 work time for the process under this reagent system. The screen analysis of the flotation concentrate indicates that this reagent system has a better effect on the flotation of +0.074mm particles, and a bad effect on the flotation of-0.045mm particles.

Iron Grade

The copper-iron ore has grades of 0.58% Cu and 42.14% Fe in Anhui. According to test on raw ore, it has the characteristics of close intergrowth and fine dissemination size, which belongs to a refractory ore. The copper oxide distributes mainly at the perimeter of copper sulfide. According to the characteristics of the structure, a flow sheet of rough grinding and flotation of inter-locked particles is taken. This process can recover copper effectively, leading to the recovery of Cu increase to 70.05%.A combined technological process of high intensity magnetic separation-gravity separation is used to hematite, which achieves an iron grade of 62.34% in the final concentrate and a recovery of 65.49%.

Kyanite is a kind of andalusite minerals, with good refractory. In nature, it existed together with mica, quartz etc, so it is necessary to purify. Garnet kyanite schist in Hebei province as the raw ore was separated in this paper, on the basement of high intensity magnetic separation and gravity to demilish impurities, obtain kyanite rude concentrate, by proceed a series of flotation condition test research, through six- concentrate reelection, getting the flotation concentrate with grade of 56.16%,the productivity of 12.09%,the recovery of 36.82%. Meanwhile, the reason of the low concentrate grade was analysed, and the suggestion was given to deal with kyanite concentrate in the next step. It provided foundation date for the developing of kyanite separation.

Iron Concentrate

An iron ore contains specularite and hematite which are its main iron minerals. And its main gangue minerals are specularite, part of the clay material and a small amount of quartz.Tests are made on the ore by adopting processes including gravity separation, high intensity magnetic separation, high intensity magnetic-gravity separation and high intensity magnetic - reverse flotation. The test results show that the separation process of high intensity magnetic-reverse flotation can obtain an iron concentrate grading about 66.62% at a recovery of 58.38％ from an iron ore assaying around 35.00% iron, rather good metallurgical performances.

Recent Developments

The recent developments of steel and iron industries generated a huge consumption of iron ores which has attracted much attention for utilizing low-grade iron resources to satisfy this increasing demand. The present study focuses on the characterization and enrichment of the low-grade iron ores from Rouina deposit-Ain Defla-. Currently, the ore is used in the cement industry because it is considered a low-grade iron ore. After the sampling process, a physico-chemical and mineralogical characterization was carried out and the results revealed that the sample consists of hematite, limonite and goethite as major opaque oxide minerals whereas silicates as well as clays form the gangue minerals in the sample. The average grade of FeTotal, SiO2 and Al2O3 contents in the raw material collected from the mine of the case study are 30.85%, 23.12% and 7.77% respectively. Processes involving combination of classification, washing and dry high-intensity magnetic separation were carried out to upgrade the low-grade iron ore sample to make it suitable as a marketable product. The sample was first ground and each closed size sieve fractions were subjected to washing followed by drying than dry high intensity magnetic separation and it was observed that limited upgradation is possible. As a result, it was possible to obtain a magnetic concentrate of 54.09% with a recovery degree of 89.30% and yield of 62.82% using a magnetic field intensity equal to 2.4 Tesla at the size fraction [-0.125 +0.063 mm].
