Aluminium Projects

Spanish  French   Italian   Deutsch   Portugues
Aluminum is known for its corrosion resistance ability owing to the phenomenon of passiveness and the low density of metal. The presence of bauxite makes it possible as it is the third most abundant element available.

The aluminum is extracted from bauxite with (sp gravity – 2.5 – 3) and consists of 31 – 52% of Alumina (Avg – 41% ). The reason why aluminum production is less than iron in-spite of the fact that raw materials are more available are, the cost (1019$/ton) of the extraction process is higher. The 60 – 70% of the costing in aluminum goes in refining and power consumption (153 MJ – Avg).

There are two main processes involved.

Copper Projects

Copper is a ductile metal with very high thermal & electrical conductivity. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. Most copper is mined or extracted as copper sulfides from large open pit mines.

Copper is produced primarily by pyrometallurgical smelting methods. Pyrometallurgical Smelting process include 4 steps - Roasting, Smelting, Concentrating & Fire Refining. The 4 smelting furnace technologies used are Reverberatory, Electric, Noranda, and Flash.

The reverberatory furnace smelting operation is a continuous process, with frequent charging and periodic tapping of matte, as well as skimming slag. Heat is supplied by natural gas, with conversion to oil during gas restrictions. Furnace temperature may exceed 1500, with the heat being transmitted by radiation from the burner flame, furnace walls, and roof into the charge of roasted and unroasted materials mixed with flux.

Electric arc furnace smelters generate heat with carbon electrodes that are lowered through the furnace roof and submerged in the slag layer of the molten bath. The feed consists of dried concentrates or calcine. The chemical and physical changes occurring in the molten bath are similar to those occurring in the molten bath of a reverberatory furnace.

The Noranda process, allowed the continuous production of blister copper in a single vessel by effectively combining roasting, smelting, and converting into 1 operation. The Noranda process uses heat generated by the exothermic oxidation of hydrogen sulfide. Additional heat is supplied by oil burners or by coal mixed with the ore concentrates.

Flash furnace smelting combines the operations of roasting and smelting to produce a high-grade copper matte from concentrates and flux. In flash smelting, dried ore concentrates and finely.

ground fluxes are injected together with oxygen and preheated air (or a mixture of both), into a furnace maintained at approximately 1000. As with the Noranda process reactor, and in contrast to reverberatory and electric furnaces, flash furnaces use the heat generated from partial oxidation of their sulfide charge to provide much or all of the required heat.

At MHL we facilitate the copper projects.

Ferro Alloys Projects

Ferro alloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese, aluminium & silicon. It is used in the production of steels and alloys as a raw material.

The alloy impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the leading consumer of Ferro alloys. Ferroalloys are produced generally by two methods- more commonly, ferroalloys are produced by carbothermic reactions, involving reduction of oxides with carbon (as coke) in the presence of iron. Some ferroalloys are produced by the addition of elements into molten iron.

Cement Projects

Rapid increase in construction and heavy industry has led to spur in the demand of Cement & Gypsum. Cement used for construction is categorized as hydraulic or non-hydraulic. Cement finds major application in production of mortar and concrete - the bonding of natural or artificial aggregate to form a strong building material, which is durable in the face of normal environmental effects. Hydraulic cement refers to any cement that will set and harden after being combined with water. After hardening this kind of cement will retain its hardness and strength even under water. Most of the construction cements today are hydraulic. Non-hydraulic lime is primarily composed of calcium hydroxide (generally greater than 95%). It comprises material such as lime and gypsum plasters, which must be kept dry in order to gain strength.

Cement manufacturing as a process and as a core industry has undergone many stages of transformation in recent years. MHL holds deep domain knowledge of the industry and hence, is equipped to offer customized service that are directed to meet the needs of clients from cement plants. We can also supply finest quality of gypsum for this project. MHL is capable of providing turnkey project for complete Plant of Cement. We execute turnkey cement projects for Cement Plants, Rotary Kiln Cement Plants, Vertical Shaft Cement Plants, Clinker Grinding Units, Slag Cement Grinding Units and Slag Grinding Project.
