In recent years, lead and zinc mining technologies have improved significantly. Mineral concentration process and lead and zinc mining equipment, technical and economic indicators have reached the world advanced level. Polymetallic sulfide ore flotation process has made significant progress; the flotation of new technology and mixed concentrate of the high alkalinity asynchronous flotation process in lead and quartz processing plant.
Lead and zinc, most of the co-existence is an ore body, in general, lead and zinc mining, beneficiation constitute a joint enterprise. Lead and zinc processing plant using cyanide-free process has been more than 40%; oxide mineral concentration has made new progress, and find appropriate in the lead-zinc material composition of complex, embedded in the fabric grain fine and mineral mud and large amount of oxidized lead and zinc mining process. The successful development of limestone mining processing plant catch to take strong and good selectivity, low toxicity, etc.; key beneficiation grinding and delivery process, the microcomputer control.
The lead and zinc smelting fire and wet coexist, production capacity is about half and half. Pyrometallurgical zinc smelting, process improvement, such as Huludao Zinc Plant vertical tank cavity size has reached the width × length × height 310 × 4610 × 10900mm2 heated area of 100m2, Nissan zinc 20t, the recovery was 94.07%. Blast furnace smelting lead and zinc technology using sealed wood new achievements. Sintering machine area has reached 110m2, the use of rigid slide seal,stone crushing plant for sale, multi-point engagement structure, good sealing, easy sintering sulfuric acid.
The wet smelting lead-zinc fever acid leaching process has been used in production; traditional wet smelting lead-zinc technology is successfully used two consecutive leaching technology; achieve a boiling layer of continuous purification in addition to copper, cadmium: a tubular filter machine to filter the net liquid slurry. Zinc smelting DC power consumption down to 2966-3160k.Wh / t. All of our refining lead and zinc process everything that has built a multi-process, multi-product, a better recovery of lead and zinc industrial system.

Malaysia has large resources of tin. Most of the high-grade tin reserves, however, were depleted or are beneath developed lands. Malaysia has substantial resources of such tin- associated minerals as ilmenite, monazite, struverite (a columbium (niobium)/tantalum-bearing mineral), and zircon; natural gas and crude petroleum. Other important mineral resources are barite, bauxite, carbonate rocks, clays, coal, copper, gold, iron ore, and silica.
