Investment opportunities in industrial minerals in Yemen

Yemen is characterized by the occurrence of minerals and industrial rocks in large quantities and good quality.  As many of the deposits occur close to infrastructure and this will facilitate commercial development of these deposits.  with the majority of them being concentrated in,, populated areas having the necessary infrastructure and facilities to  ease the investment process. These minerals and rocks include limestone, gypsum, perlite, pumice, saltpeter, clay minerals, silica sandstone, scoria, zeolite, feldspar, quartz and silica sand. Yemen is also contains an featured by the abundance of building and decoration stones of high quality standards such as granite, gabbro, marble, basalt, tuff and ignimbrite.


Based on the implemented geological studies, the investment opportunities in industrial minerals and rocks have been identified in a number of fields such as the manufacturing of cement, glass, ceramic, gypsum, rock wool, chemical industries, salt production and building and decoration stones. Such opportunities may be summed up as follows:

1. Natural Zeolite:

Natural zeolite ores in Yemen occur in abundant quantities estimated at over 200 million cubic meter with multiple commercial types of international standards such as clinoptilolite, heulandite and mordinite. Mineral analyses have revealed a high purity of zeolite minerals of up to 95% in some areas. Chemical tests show a decline in the iron ferrite and magnesium percentages and faced by increasing amounts of sodium, potassium and calcium. Based on their chemistry, these zeolite minerals are pure by international standards and may have In light of the mineral and chemical studies anthe comparison with similar international sediments, it becomes clear how pure the ores are and potentials of using such ores in various applications such as; oil refining as an intermediate material, paper, detergents and plastic manufacturing, cement and drilling fluids production, natural gas and sewerage water purification, soil additives to improve the yields, treatment of the barns' wastes and absorption of odors and additives to the animal fodder. The most important investment opportunities in zeolite can be listed as follows:
