Agnico Eagle Finland Oy

Description

The Kittilä mine belongs to the Canadian mining company Agnico Eagle Mines Ltd, which owns nine mines in three countries (Canada, Mexico and Finland). The company is doing exploration in Canada, the USA, Mexico and Scandinavia. The mining company provides employment for approximately 6,700 people, including contractors.

The company’s only mine in Europe is located in Kittilä, Finland, where it is also registered. The Kittilä mine is also the largest gold mine in Europe. The mine has been in operation for about seven years, with the annual production of gold amounting up to this point at approximately 5,300 kg. The first dore bar was poured in January 2009.

Operations at the mine were launched in 2008 with open pit mining, which drew to a close in late 2012. Today there is underground-only operation. Excavated ore is transported from the mine on mine trucks and is either stored in temporary stockpiles or carried directly to the crushing facility from where it is transported on belt conveyors for milling. In flotation – the phase of the process following milling – sulphides attach themselves onto air bubbles which rise to the surface, where they are skimmed and led to autoclave oxidation. In an autoclave, under a high pressure and temperature and aided by an additional injection of oxygen into the autoclave, a process is induced that releases the refractory gold present in the ore. The resulting sludge is leached and conducted to a dissolution circuit, in which the dissolved gold is adsorbed in adsorbent carbon. From absorbent carbon, gold is recovered via acid extraction, after which it is electroplated onto stainless steel wool and poured into bars.

After the gold extraction tailings are pumped to the tailings ponds. Tailings resulting from the flotation and cyanide dissolution processes are stored in separate ponds.

Sludge from the cyanide dissolution process is led to a cyanide destruction process before it is pumped into a pond, in order to ensure that any cyanide residues that may not have been dissolved will be chemically broken down and rendered harmless. Water in the ponds is recycled back to the process, and part of the water used in the flotation stage is pumped, via a treatment peatland, into the recipient waterway (the Seurujoki River), in accordance with the environmental permit.

Part of the flotation tailings and waste rock is used for the pit backfill, and part of the waste rock is hauled by mine trucks to the surface level to be exploited for construction of ponds and roads or dumping.

About exploration

Agnico Eagle Finland Oy has carried out exploration since 2006. The company has valid claims and exploration permits amounting to 26,345 hectares (numbering 228). Exploration areas are thought to contain gold at least. In exploration Agnico Eagle Finland Oy makes use of deep-hole diamond drilling, prospector’s hammer and soil sampling, groove sampling, sampling using mini drilling rig machines (the sampling of rock), geophysical measurements, exploratory trenches dug using hand-held tools, exploratory trenches dug using an excavator, bedrock mapping and the sampling of glacial till. A total of 73km of deep-hole deep drilling was carried out in 2015. No permits concerning the exploration areas are known to be subject to appeal.

Impact on the use of neighbouring areas and the sources of livelihood

Sidosryhmäyhteistyö: Impact on local sources of livelihood: Areas of Reindeer Owners’ Association in which mining and exploration are carried out are Kuivasalmi (24,470 ha), Sattasniemi (1,558 ha) and Oijärvi (2,018 ha). Of the area of the Kuivasalmi Reindeer Owners’ Association, approximately 0.024 % (1,163 ha) is covered by the mining concession. Municipalities, the inhabitants of the neighbouring areas, entrepreneurs in tourism, environmental organisations and reindeer owners’ associations are recognised as being the most important stakeholders of the company, and are taken into consideration in the work carried out with them. Furthermore, the mining company stocks the recipient waterway (the Seurujoki River) with trout juveniles, in accordance with its stocking obligation.   Impact on the recreational use of the neighbouring areas:   According to the assessment of the company itself, its activities have not impacted the recreational use of the neighbouring areas.   Impact on the landscape value: Landscape values have been taken into account in the operations of the company. The maximum height of the stockpiling ares of waste rock has been proportioned to the height of other reference points in the area. Endangered plants have been replanted in the botanical gardens of Universities of Oulu and Joensuu. Efforts have been made to minimise tree felling in the area of the mining concession.
