Kati makes biofuel drilling switch at Keliber lithium project

Oy Kati Ab, a drilling contractor, has started to use biofuel in the drill rig operating at Keliber’s lithium exploration site in Central Ostrobothnia, Finland.

Tapani Niskakangas, Acting Managing Director at Kati, said: “Taking the environment into consideration and minimising the negative impacts is a guiding principle for us at Kati as well as Keliber. When we learned that Neste MY Non Road Diesel™ was available also in northern Finland this autumn, Keliber was the first company we proposed to introduce it, and we received a positive answer right away.”

According to calculations made at Kati, the switch from regular fuel oil to biofuel makes it possible to reduce emissions by at least 50%. It is estimated that, during 2020, drilling at the Keliber work site generated emissions of 78.04 t of CO2e, of which 95.2% was caused by fuel usage. If biofuel had been used, the estimated emissions would have been 37.90 t CO2e or 51% less. The emission reduction (40.14 t CO2e) is equivalent to a 286,714.3 km journey by car.

Keliber’s CEO, Hannu Hautala, regards the fuel switch as a good example of sustainable operation, which Keliber is committed to: “We are continuously looking for ways to reduce our environmental impact and improve our operations when new possibilities emerge. I am happy about this opportunity to switch to renewable energy at the drilling site.”

Kati started to use biofuel at the Keliber site during the second week of December. According to Niskakangas, the switch was easy: the machines run on biofuel as smoothly as they do on fossil fuels. And there is an added safety benefit as biofuels do not endanger water organisms or human health. This more than offsets the additional 25% price tag for biofuel over fossil fuels, which translates into an increase of about 2% in the total drilling cost.

Niskakangas said: “Keliber is the first of our customers to use biofuel. We are interested in expanding its use, but its popularity has a lot to do with logistics. Today, we transport the MY renewable fuel from Kemi harbour to our storage tank in Kalajoki.”

Kati has been working with Keliber on its lithium project for some 20 years. In recent years, Keliber has had continuous exploration and resource drilling operations, and the annual total drilling has varied from 10-20 km.

The planned Keliber operations include lithium mine sites and a concentrator plant in Kaustinen, Kokkola and Kruunupyy, and a lithium hydroxide plant in Kokkola.

FLSmidth to provide process engineering input for Keliber’s lithium project

Keliber says it has appointed FLSmidth to provide process engineering services at its Päiväneva concentrator plant in Finland.

The two parties have reportedly agreed on the provision of process, layout and mechanical engineering services at the concentrator.

Hannu Hautala, CEO of Keliber, said: “We have chosen a partner with considerable experience in the mining industry, including lithium production. Our goal is to build a world-class plant that utilises the best available technology, which means safe, environmentally friendly and cost-optimised production.”

Mikko Keto, Mining President at FLSmidth, added: “We are delighted to receive this process engineering order from Keliber. It is a strong proof point of our know-how in the lithium arena, where we have been a leading provider of high-performing equipment, solutions and expertise for well over 20 years. We now look forward to this next step of designing an efficient, world class, concentrator flowsheet, in line with our MissionZero program.”

The award of the contract regarding the concentrator plant continues Keliber’s cooperation with FLSmidth, which will soon also see the completion of the basic engineering of high temperature conversion rotary kiln technology at Keliber’s chemical plant, located in Kokkola.

The concentrator will be built in the Päiväneva area of Finland, which is located on the border of the municipalities of Kaustinen and Kruunupyy, and within the immediate vicinity of Keliber’s lithium deposits. At the concentrator plant, ore will be processed into spodumene concentrate, which will then be transported to the chemical plant in Kokkola, where it will be further processed into lithium hydroxide.
