The L-P-CF process developed by the authors consists of 1)leaching refractory copper ore or middling by H_2SO_4,2)chnging Cu~(++)into colloidal copper sulphide precipitate and 3)carrier-flotation by using a high-grade Cu concentrate for adsorbing and carrying the fine copperish particles.Experiments on several kinds of Cu ores have been made and quite satisfactory results have been obtained in our laboratory. For example,an ore sample from Dongchuan Copper Mine,was floated to yield a high-grade concentrate and a middling.Then,the middling was treated with the L-P-CF process,using the concentrate as carrier.A final concentrate grade of 22.5% Cu and a recovery of 81.5% were achieved,which exceeded those obtained by conventional flotation process by 4-5% and 7-8% respectively.Another sample assay- ing 2% of Cu from Dayie Copper Company,yielded a concentrate with an assay of 24.9% Cu and recovery of 81.2% through the L-P-CF process,while the conventional flotation process only gave a concentrate grade of 15% Cu and a recovery of 35%. It is believed that the L-P-CF process may have some advantages over the other chemical processes for Cu ores,e.g.:1)it does not involve any solid-liquid separation in the process;2)no extractants,ion-exchangers or sponge iron are needed,3)flotation is performed in neutral or weak acid pulp;4)precious metals,such as Au,Ag,can be recovered together with Cu;5)flotation process can be greatly improved by using Cu concentrate as carrier,which is available to any plant and does not need regene- ration and reuse;6)using CaS as a precipitant of Cu~(++)and CaCO_3 for neutralizing free acid may provide favourable conditions for treatment of waste water.

本文提出的浸出—沉淀—载体浮选法(简称LPCF法)用以处理硅铝型、钙镁型和铁锰型的难选铜矿石和中矿取得了较好结果。精矿品位高于20%,铜回收率比常规浮选法高6~40%。在我国,用选冶工艺处理难选铜矿石的研究,已进行了多年,由于若干重大技术经济问题尚未解决,用于生产的为数不多。我们的研究目的是在前人研究成果的基础上,寻求一种易于工业化的难选铜矿石的化学选矿方法。浸出—沉淀—载体浮选法,对三种不同类型的难选铜矿石及其浮选中矿进行小型试验,获得了较好的结果。

The ore mineral assemblage of Dayishan wollastonite deposit is complex being composed of wollastonite, diopside, idocrase, K—feldspar, albite, calcite and quartz. To evaluate the ore deposit, it is necessary to determine the content of wallastonitt in the ore. The results from the petrographical study lack of representation. The paper has introduced the method of using the analytical data of chemical composition of the ore in conversion of the wollastonite content.

大义山硅灰石矿床矿石矿物组合复杂,由硅灰石、透辉石、符山石、钾长石、钠长石、方解石、石英等组成。矿床评价需要测定矿石中的硅灰石的含量。岩矿鉴定用薄片测定的结果缺乏代表性。本文介绍了用矿石化学成分分析数据换算成硅灰石含量的具体步骤。

The chemical weathering of manganese ores under dry climate condition is controlled by the fugacities of O_2, CO_2 and S_2 in the atmosphere and soil and the manganese minerals are occurred in solid phase transformation without migration of Mn and Fe elements. Manganese minerals of low valecy are not stable on the earth surface and easy to be oxidized into high valency manganese compounds which are stable and easy to form secondary high grade manganese ores. The manganese ores in carbonatite formation may be...

The chemical weathering of manganese ores under dry climate condition is controlled by the fugacities of O_2, CO_2 and S_2 in the atmosphere and soil and the manganese minerals are occurred in solid phase transformation without migration of Mn and Fe elements. Manganese minerals of low valecy are not stable on the earth surface and easy to be oxidized into high valency manganese compounds which are stable and easy to form secondary high grade manganese ores. The manganese ores in carbonatite formation may be secondarily enriched while those in clastic rock formation are easy to be migrated or washed away. This difference is a chief obstacle for manganese ore exploration.

干燥气候下,锰矿石的化学风化受大气和壤中O_2、CO_2、S_2逸度控制,锰矿物呈固相转变,不存在Mn、Fe元素迁移现象。热带、亚热带潮湿气候,低价锰矿物不稳定,地表易氧化成高价锰;高价锰矿物稳定,易形成次生富锰矿。碳酸盐建造中锰矿可次生富集,碎屑岩建造中锰矿易流失迁移。这种差异是锰矿找矿中的主要障碍。
