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.

The mineral processing flow sheet and reagent system of flotation copper minerals from a large copper-iron deposit in Yunnan were fully investigated. The results indicate that the optimum conditions for flotation of copper minerals from the material were identified as grinding fineness of 85%, dosage of CaO at 2000g/t , dosage of Na2S at 200 g/t, dosage of butyl xanthate 40g/t. Under such a condition, a copper recovery of 88.17% with a concentrate grade of 26.86% was achieved from the material using a closed circuit flow sheet of "one-stage roughing flotation, one-stage cleaning flotation and one-stage scavenging flotation.

High intensity magnetic separation tests have been carried out on the oolitic limonite ore with complex relations between limonite and gangue minerals of Honghe prefecture, and a optimal flowsheet for recover limonite from run-of-mine was adopted at last. High intensity magnetic separation flowsheet with one stage rougher, cleaner and scavenger, which have been studied respectively. Iron concentrate containing 55.18%Fe could be obtained at yield of 53.20% and recovery of Fe 68.45 % in closed circuit test.

Because of oolitic hematite micro-fine disseminated and complex structure and other characteristics, has been considered the world's mineral processing problems. This paper studies the use of its current situation in China and some traditional sorting techniques such as strong magnetic separation - reverse flotation, flocculation - intensity magnetic separation, magnetic roasting - magnetic, and discuss an efficient sorting technique - the deep reduction, which has important practical significance for oolitic hematite sorting.

The mineral processing experimental research was carried out on a high mud content lean hematite. The results showed that using the technological flowsheet of “stage grinding- low intensity magnetic separation for obtaining concentrate - high-intensity magnetic separation for discarding tailings-gravity separation(shaking table)”,a final iron concentrate with TFe grade of 65.89% ,yield of 19.35% and iron recovery of 52.32% from the raw ores with TFe grade of 24.07% was obtained, with the first stage grinding size being 50% -200 mesh and the second stage,95% -200 mesh.

With the depletion of mineral resources, more attention is paid on the secondary resources to recover valuable metals. In this paper, a research is carried out to recover copper and iron from copper smelting slag by flotation and magnetic separation. The influence of grinding fineness and collectors on flotation of copper are investigated. A copper concentrate is obtained by flotation and an iron concentrate is obtained by magnetic separation in the closed circuit flowsheet. The copper concentrate contains 18.86% Cu with a recovery of 72.36%, and the iron concentrate contains 52.24% Fe with a recovery of 70.87%.

A beneficiation experimental research is conducted on sulfur-containing 18.17% multi-metals tailings. On the basis of the traditional mineral processing technology, it introduces X-51, a new type sulfide mineral activator, to instead of copper sulfate. Eventually, the sulfur concentrate grade is 47.51% with the recovery of 92.11%. The effectively recovery of the sulfur is creating good economic benefits and environmental benefit.

The main elements can be recovered for mineral processing in a mineral containing titanium of Baoding area were Ti, Fe and V, and the elements in the main gangue minerals were Si and Al. Gravity concentration, gravity concentration-high intensity magnetic separation and gravity concentration-flotation tests were performed on the ore sample respectively. The results showed that, in the test of shaking table, when the grinding fineness was -0.074mm 93%, the productivity of concentrate can reach 32.24%; when grinding fineness was -0.074mm 93%, after gravity concentration-magnetic separation, 30.25% of concentrate productivity can be attained; when the grinding fineness was -0.074mm 85%, after gravity concentration-flotation, the productivity of concentrate was 3.31%. Maybe it's the condition of the tests wasn't controlled well, especially adjusting pH value in the flotation stage, it's hard to control, so the results were not very good.

Iron ore minerals are mainly silicate-type iron minerals in raw ore, and its distribution rate was 51.93%; followed by magnetic iron, and its distribution rate was 36.81%; content and distribution rate of other minerals was very low; element grade of iron, phosphorus, sulfur, silica were 11.90%, 0.043%, 0.013% and 45.23%, the main gangue were silica and calcium oxide, recyclable iron minerals mainly is magnetic iron mineral. Due to the grade of iron of raw ore and the amounts of optional magnetite was relatively little, in order to investigate the optional of low-grade ore, weak magnetic separation test and weak magnetic separation tailings-strong magnetic separation test were put into effect.
