|Bulk material handling is used for the handling of dry materials
such as ores, coal, sand, gravel and stone in loose bulk form. It can
also relate to the handling of mixed wastes. The purpose of a bulk
material handling facility may be to transport material from one of
several locations (i.e. a source) to an ultimate destination or to
process material such as ore in concentrating and smelting or handling
materials for manufacturing.
|Mining is the extraction of valuable minerals or other geological
materials from the earth from an orebody, lode, vein, seam, or reef,
which forms the mineralized package of economic interest to the miner.
Ores recovered by mining include metals, coal and oil shale, gemstones,
limestone, and dimension stone, rock salt and potash, gravel, and clay.
Mining of stone and metal has been done since pre-historic times. Modern
mining processes involve prospecting for ore bodies, analysis of the
profit potential of a proposed mine, extraction of the desired
materials, and final reclamation of the land after the mine is closed.
|In the fields of architecture and civil engineering, construction
is a process that consists of the building or assembling of
infrastructure. Far from being a single activity, large scale
construction is a feat of human multitasking. Normally, the job is
managed by a project manager, and supervised by a construction manager,
design engineer, construction engineer or project architect. For the
successful execution of a project, effective planning is essential.
Involved with the design and execution of the infrastructure in question
must consider the environmental impact of the job, the successful
scheduling, budgeting, construction site safety, availability of
building materials, logistics, inconvenience to the public caused by
construction delays and bidding, etc.
|It is the process of removing contaminants from waste water and
household sewage, both runoffs, domestic, commercial and institutional.
It includes physical, chemical, and biological processes to remove
physical, chemical and biological contaminants. Its objective is to
produce an environmentally safe fluid waste stream (or treated effluent)
and a solid waste (or treated sludge) suitable for disposal or reuse
(usually as farm fertilizer). Using advanced technology it is now
possible to re-use sewage effluent for drinking water.
|Metallurgy is a domain of materials science and materials
engineering that studies the physical and chemical behavior of metallic
elements, their intermetallic compounds, and their mixtures, which are
called alloys. Metallurgy is also the technology of metals: the way in
which science is applied to the production of metals, and the
engineering of metal components for use in products for consumers and
manufacturers. The production of metals involves the processing of ores
to extract the metal they contain, and the mixture of metals, with
perhaps other elements, to produce alloys. Metallurgy is distinguished
from the craft of metalworking. Metallurgy is subdivided into ferrous
metallurgy (sometimes also known as black metallurgy) and non-ferrous
metallurgy or colored metallurgy. Ferrous metallurgy involves processes
and alloys based on iron, while non-ferrous metallurgy involves
processes and alloys based on other metals. The production of ferrous
metals accounts for 95 percent of the world metal production.
|The power plant is the unit that facilitates the generation of
electric power with the help of generator that converts mechanical power
into electrical power. A relative motion field is generated between
conductor and magnetic field.
The power plants use natural gas, coal and oil as the fuel that harnessed the generators. These fuels are cheap and easily available and goes well with the type of technology that are easily available with the power providing company. The companies may also use nuclear power for electricity generation and also go towards more cleaner and natural resources like hydroelectric waves, solar and wind.
|Chemical plant is an industrial process plant that manufactures
chemicals, usually on a large scale. The general objective of a chemical
plant is to create new material wealth via the chemical or biological
transformation and or separation of materials. Chemical plants use
special equipment, units, and technology in the processes. Other kinds
of plants, such as polymer, pharmaceutical, food, and some beverage
production facilities, power plants, oil refineries or other refineries,
natural gas processing and biochemical plants, water and wastewater
treatment, and pollution control equipment use many technologies that
have similarities to chemical plant technology such as fluid systems.
Some would consider an oil refinery or a pharmaceutical or polymer
manufacturer to be effectively a chemical plant.
