Los Colorados Mine
Los Colorados is an open-pit iron mine in northern Chile about 45 km northeast of the port of Huasco. The ore of the mine is one of various iron oxide-apatite (IOA) ores that are part of the north-south Chilean Iron Belt. The mine opened in 1997 and in 2021 it had a production of 2,559,000 metric tons of iron. It is owned by Compañía Minera del Pacífico (CMP). The mine is considered a replacement for El Algarrobo a nearby mine that became exhausted of profitable ore in the 1990s. Its planned cut-off grade in the 1990s was 30% Fe. Currently the mine feeds iron ore to the pelletizing plant Planta de Pellets at the coast in Huasco for the manufacture of iron pellets. It produces annualy 4.5 million metric tons of pellets. Besides this, Los Colorados mine feeds the inland Planta Magnetita in Tierra Amarilla (which also receives tailings from Candelaria). From Planta Magnetita ore concentrate is transported in a pipeline for 120 km to the port of Punta Totoralillo. In 2025 t ...

Pellet (steel Industry)
Pellets are a processed form of iron ore utilized in the steel industry, specifically designed for direct application in Blast furnace, blast furnaces or direct reduction plants. These pellets are spherical in shape, with diameters ranging from 8 to 18 millimeters. The production of iron ore pellets involves several steps, including grinding the ore, mixing it with binders, and then forming and heating the pellets. The iron content of the pellets generally ranges from 62% to 66%. This enrichment process improves the iron concentration and imparts specific chemical and mechanical properties that enhance the efficiency of steel production. History The pelletizing of powdered iron ores was first introduced at the end of the nineteenth century, utilizing tar as a Binder (material), binding agent, comprising 1% by weight. This method involved firing the mixture in a rotating drum to create pellets suitable for blast furnaces, while also facilitating the removal of undesirable eleme ...

Open-pit Mines
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock (geology), rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous industrial sector, sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iron Ore Mines In Chile
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechanical properti ...

Environmental Impact Assessment
Environmental impact assessment (EIA) is the assessment of the environmental impact, environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action. In this context, the term "environmental impact assessment" is usually used when applied to actual projects by individuals or companies and the term "strategic environmental assessment" (SEA) applies to policies, plans and programmes most often proposed by organs of state. It is a tool of Environmental management system, environmental management forming a part of project approval and decision-making. Environmental assessments may be governed by rules of Administrative law, administrative procedure regarding public participation and documentation of decision making, and may be subject to judicial review. The purpose of the assessment is to ensure that decision-makers consider the environmental impacts when deciding whether or not to proceed with a project. The I ...

Punta Totoralillo
Punta Totoralillo is an industrial port for export of mining products of Atacama Region, Chile. The port serves the iron mine of Cerro Negro Norte and receives iron ore concentrate (>66% Fe) from Planta Magnetita through a 120 km-long buried pipeline. Planta Magnetita processes the tailings In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different from overburden, which is the waste rock or other material ... of the copper mine of Candelaria and some of the iron ore of Los Colorados.

Candelaria Mine
The Candelaria mine is a large open pit and underground copper-gold mine located in northern Chile in the Atacama Region. Candelaria has Proven and Probable Reserves of 676 million tonnes of ore grading 0.53% copper, 0.13 g/t gold, and 1.79 g/t silver; containing 3.58 million tonnes of copper, 3.0 million oz of gold and 39 million oz of silver. The mine project incorporates a reverse osmosis plant at the port of Caldera, commissioned in 2013, with a capacity to produce 500 litres per second of desalinated industrial water, piping it 115 km from the Pacific Ocean to the minesite. The project was operated since discovery in 1987 by Phelps Dodge Corporation, which was taken over by Freeport-McMoRan in 2007. Lundin Mining bought out Freeport's 80% stake in 2014.
