High Carbon Ferrochrome
Ferrochrome is the most important raw material for stainless steel production. It is mainly used in the production of stainless steel, ball bearing steel, tool steel, nitriding steel, heat-strength steel, quenched and tempered steel, carburizing steel and hydrogen-resistant steel. Because chromium plays a decisive role in stainless steel, there is only one element determining the nature of stainless steel, that is, chromium, each stainless steel, they must contain a certain amount of chromium. As our company's supporting products, the annual production capacity of high carbon ferrochrome is 300,000 tons.

Silico-Manganese Alloy
Alloys consisting of manganese, silicon, iron and a small amount of carbon and other elements are ferroalloys with wide applications and large output. Manganese-silicon alloy is a common Compound Deoxidizer in steelmaking, and a reductant in the production of medium & low carbon ferromanganese and metal manganese by electro-silicothermic method. The annual design capacity of this project is 1 million tons, which is also one of the main supporting products of our company.
Manganese Metal Ingot
In this project, landing manganese, crushed manganese and washed manganese produced in the production of electrolytic manganese metal are used as raw materials to remelt and produce national standard manganese ingots. According to the market demand of manganese series products and on the basis of the production process of wet electrolytic manganese metal, a new technological innovation project has been developed, which has derived the industrial chain of electrolytic manganese and increased the variety of products.
Sulfuric Acid
The sulfuric acid produced by our company is a kind of high purity sulfuric acid with 93% and 98% concentration respectively. It is a colorless oily liquid with a mass fraction of 98.3% and a density of 1.84g/cm3. It is a strong acid with high boiling point and difficult to volatilize. It is soluble in water and can be mixed with water at any ratio. It has strong oxidation, dehydration and water absorption.  This product is widely used in metallurgy, fertilizer, drugs, explosives, pigments, detergents, batteries, chemical reagents, dehydrating agents, sulfonating agents and national defense, atomic energy industry and rocket technology.
Selenium Dioxide
Selenium dioxide project was put into operation in 2015. The production process control is centralized by advanced DCS system, which has high safety performance. Through the group company's vigorous support to improve the process, from the oxidation furnace heating mode and equipment rationality for technological transformation, now can reach 90 tons per month, annual capacity of about 1500 tons. Selenium dioxide is an irreplaceable additive in the process of electrolysis of manganese metal. Selenium dioxide can promote the electrochemical behavior of electrolytic manganese and inhibit the precipitation of hydrogen.
SDD Project was put into operation in September 2016. This project is the most advanced design and the best technological process in China at present. Through the comprehensive technological transformation in 2017, the annual production capacity of SDD is about 15,000 tons. SDD is used to separate the heavy metal ions in solution-making and after-processing section in EMM combination workshop.
Selenium dioxide and SDD are indispensable additives for electrolytic manganese metal, which play an important role in the quality and output of manganese metal production.
Waste Heat Power Generation
Ningxia Tianyuan Manganese Group currently has three waste heat power generation projects, mainly for the waste heat power generation section of Ningxia Tianyuan Construction Material Co., Ltd. The generating unit is a pure condensing turbine unit with installed capacity of a single 9MW, estimated annual power generation capacity of 49.92 million KWH; Ningxia Huaxia Resources Comprehensive Utilization Co., Ltd.  Sulfuric acid plant, boiling furnace waste heat power generation project, the generating unit is extraction condensing turbine unit, installed capacity is a single 6MW, the estimated annual power generation capacity is 32.4 million KWH; Ningxia Tuanyuan Power Generation Co., Ltd. smelting furnace tail gas recovery resources comprehensive utilization power generation project, the unit is extraction condensing turbine unit, installed capacity is 3X12MW, the generator capacity is 3 X15MW and the annual power generation is expected to be 234.63 million KWH.
