31 Vanadium seldom forms mineral deposit. It is mainly exist in vanadium titanomagnetite coal gangue and claystone.

32 The ore is composed of 30 kinds of minerals, the nickel mineral is mainly nicopyrite and the gangue minerals are chlorite, talc and so on.

33 The ordinary portland cement of 425R type was produced by the industrial waste slags, gangue, liquid slag, phosphate slag, manganic slag and phosphogypsum.

34 An industrial analysis of the segregated abnormal coal particles disclosed that it consisted of a blend of gangue, bitumite and anthracite, with an anthracite content of 31.56%.

35 The selective depression of ammonium fluorosilicate on aegirite, an iron-containing silicate gangue mineral, in hematite flotation using sodium oleate collector was investigated.

36 It is applied to conveying such bulk material as all kinds of coal, gangue, ore, waste stones, etc. in collieries , mining areas, factories, building sites and so on.

37 Often the process of general mining and coal washing plant from the production process of waste rock called gangue.

38 Experiment shows that with the increment of substituted spontaneous combustion gangue powder for cement, the water demand of gelled material system is increased gradually.

39 The gangue mineral mainly consists of quartz and sericite, and then calcite, dolomite, chlorite and peat.

40 The select principle of drawing interval was given for different coal - gangue fragmental size.

41 The main gangue mineral is quartz and for 97 %.

42 Thermal activation is a good method to increase the amount of 4-coordinated Al and to improve gelatification activation of gangue.

43 Ankerite is one of the main gangue minerals genetically related to gold mineralization in the Baguamiao giant gold deposit.

44 Because of soluble copper and floatable gangue minerals in the ore, Cu-S bulk flotation technological flowsheet is adopted and obtain good metallurgical performance.

45 The mass coefficient was brought forward to assess the activity factor of original coal gangue.

46 The process parameters for furnacing gangue and configuration principle of the new type furnace are introduced in this paper.

47 The mineral composition is simple, only with original metallic minerals antimonite and pyrite, gangue minerals quartz, calcite and a few barites, all in the fissure or hole of the rock.

48 Ceramic ecological paver was investigated with solid castoff such as graphite gangue coal ash coal stone.

49 The that coal gangue from all the different regions contains the clay minerals kaolinite and muscovite.

50 Second, China stable and rapid economic growth,(www.Sentencedict.com) 2004 GDP growth of more than 9%. Road-building cement and the infrastructure development will inevitably pull gangue crusher industry's growth.

51 The paper studies the thermal reduction magnesium process with ferro-aluminum-silicon produced from carbon thermal reduction as reducing agent and kaoline coal gangue as raw material.

52 By using the Neyraudia reynediana for quick afforestation, it successfully solves the problems of difficult vegetation recovery management in the waste mines of kaolin, gold and gangue.

53 Using coal gangue slag, a new polysilicate aluminium(PSA) coagulant was prepared , by which the dyeing and steelworks dusting wastewater were treated.

54 Temperature shrinkage performance of lime and fly-ash stabilized coal gangue base course materials relates coal gangue aggregate and quality ratio of lime to fly-ash.

55 Datong kaolin resource depot in C-P period coal series strata which is chief coal gripping gangue and beds roof and floor kaolin.

56 Due to the rising price and shortage of sand, it is necessary to search for a substitute of, zircon sand. The article mainly introduces the trials on coal gangue sand to replace zircon facing sand.

57 This paper focus on the effect of groundwater level by gold gangue a model was established.

58 Some multiple texture features as the input characteristics for classifier are selected and then fused. Lastly, the neural network is used to realize the separation of coal and gangue.

59 Autoignition of gangue hill seriously pollute the environment, endanger the health of the people of the mining area.

60 Based on the characters of Chinese bauxite resources, the separation of diaspore and the main gangue, kaolinite by reverse flotation was studied preliminarily in this paper.
