In the present paper the dressing technology of wolframite ore in China and its technological results in the following operations, e. g. pre-concentration, crush- ing, gravity separation, slime treatment, cleaning rough concentrates and recovery of associated minerals are described, A common assessment is given, too. In most of wolframite mills in our country hand sorting as a pre-concentration is employed and in several mills the heavy-media separation or photometric sorting combined with hand sorting is used, by which the reject of barren rock is 50-70% from the feed. Recovery of WO_3 in this operation is 97-98%. The crushing plant flowsheet is generally performed in two or three stages in closed circuit and a few in open circuit. The size of final crushed products is minus 10 mm. The crushed products are screened into three classes of size, which is fed onto jigging. The jig tailings of coarse size and middle size are given to rod mill, and the products are send to jig again, the jig tailings are returned to the screening. The fine jig tailings are fed onto tables after classifying. The concentrates from jigs and tables are combined and cleaned either in the same mill or in a consolidated cleaning plant. The table middlings are returned to tabling or to tabling after grind- ing in rod mill. The table tailings are rejected as waste. The recovery of WO_3 in this operation is 92-93%. The slimes are treated separately. In most of mills a gravity flowsheet is adopted, in which the tables, tablecloth sluices, table-centrifugal separators are used for treating the slimes. In several mills flotation is used. The lower size limit of the table feed is 37 microns. The recovery of WO_3 in this operation is more than 70%, while the lower size limit of the centrifugal separator feed is 10 microns. The recovery of WO_3 is 60-65%. Flotation is used for roughing slimes with recovery of more than 80% WO_3. The poor tailings (above 80%) are rejected. But results of cleaning the rough concentrates by flotation are unsatisfactory. However flotation is suitable to cleaning the rough concentrates from the centrifugal separators. A method combined with flotation, gravity, magnetic separation, electrostatic separation, hydrometallurgy process, and roasting is applied for cleaning the rough concentrates. In the cleaning operation recovery above 95% WO_3 is obtained. Many associated minerals are recovered from various concentrates. The rough concentrates containing cassiterite and bismuth oxide are subjected to magnetic or electrostatic separation for recovering these minerals. Other asso- ciated minerals are recovered usually by flotation. The complexity in ore composi- tion leads to use of multistages of operation and to lower recovery. Owing to research and practice in tungsten ore treatment for 30 years in our country the poor ores are now can be treated to produce high-grade concentrates with recovery of 80-85% WO_3. Rich experience accumulated has laid solid founda- tion of further development of tungsten industry in China.

本文通过对黑钨矿选矿的几个环节:矿石的预选、碎矿、重选、矿泥选矿、粗精矿精选和伴生矿物的回收的叙述和分析,扼要介绍我国在这些方面积累的经验。说明我国黑钨选矿厂如何在原矿品位很低的情况下,获得了高品位的钨精矿和较高的回收率。文中还对我国钨矿资源的分布和地质情况作了简要的介绍。
