Velta LLC operates Mining and Separation Complex producing ilmenite concentrate

Processing Plant was built in a record eight months and opened in December 27th, 2011. The deposit has 148,9 million cubic meters of titanium ore under JORC standart and 9,45 million tons of ilmenite.

In April 2012, the produstion started to Birzulivske mine with nameplate capacity of 185 ktpa. In November 2013 the second stage of MSC was completed.

The company also owns another titanium feedstock asset – Likarivske ilmenite deposit, located in Kirovograd region as well at 7 km distance from the operational plant at Birzulivske deposit. The geological exploration permit was obtained in 2011. The drilling works have been carried out since 2012 and the ilmenite resourse base is estimated at to 3 million tons. The MSC planned to the construction will have the capacity of 120 ktpa.

Resource base of ilmenite

Ilmenite deposit was discovered in the 1960-th. In 2007 Velta has obtained the industrial mining license for 20 years for Birzulivske deposit. Since 2012 the mining and separation complex with the capacity of 300 ktpa has been operating at its base.

Byrzulivske deposit is situated in the centre of Ukraine, approximately at 200 km to the southeast from Kyiv and 250 km to west from Dnipropetrovsk. Main Black Sea ports are situated in 300 – 350 km distance from the deposit by rail. Velta has its own transportation and storage facility which is situated in Novomyrhorod – 27 km from the existing processing plant.

Resource base of ilmenite

Likarivske deposit is situated to the South of Likareve village, Novomirhorod district, Kirovohrad region, just 6 km to the East of the operating MSC at the Birzulivske mine. And actually it is the geological continuation of this very deposit.

It was discovered in 1970s of the past century alongside with Birzulivske deposit by Pivdenno-Ukrajinska geological expedition as a result of its investigation works for ilmenite sands.

Likarivske is considered as the additional resource base to the Birzulivske mining complex. In 2011 Velta obtained the geological exploration license for this deposit to the term of 5 years.

After the geological and research works leading to resource base estimation and approval Velta plans to construct a new Mineral Separation Complex of 120 ktpa nameplate capacity. Capital investments to this project are estimated at USA $50 mln.

Velta is carrying out the mining operations based on open-pit method. Before starting mining fertile soil layer is sheared and removed for temporary storage aimed to further rehabilitation.

In the open-cast sands are mixed with water by hydraulic monitors and pulp is pumped by the slurry pipe from deposit into processing plant.

Processing of the ore at the plant is carried out without any chemical additives. It has three stages:

1

Desliming

Removal of ore slimes in hydrocyclones.

2

Gravity separation

Disintegration of quartz sand and crude ilmenite (HM) by gravity separators.

3

Magnetic separation

Disintegration of quartz sand and crude ilmenite (HM) by gravity separators.

Products

Ilmenite of Byrzulivske deposit has a unique origin. The mineral features lightly rolled grains of irregular shape. The size of ilmenite grain vary from 0.05 mm to 1.50 mm.

70% of Byrzuliv ilmenite falls into grain-size category of -0.8 – +0.25 mm. Due to different stratification depth of ilmenite layer, the mineral sands have different leucoxenezation level.

In November 2012 Velta has introduced a new product separation programme based on the different magnetic features of the material. Two product Grades (Grade 1, Grade 2) have been launched into production with different content of the main elements: TіO2, FeО, Fe2О3.

This step enabled the company to provide more customer-oriented service and meet at best the requirement of chemical industry as well as metallurgical one. The approach makes Byrzulivske ilmenite completely suitable for different industrial sectors – production of titanium dioxide by sulphate as well as chloride methods, production of slag, synthetic rutile and electrodes.

Development prospects

Velta is dynamically moving ahead and is successfully implementing its development plan. The first stage realized by now is the increase of the nameplate capacity of ilmenite concentrate production to 300 ktpa by construction of the Plant #2

The next stages planned are:

  1. Expansion of the titanium resource base in Ukraine.
  2. Further company development by vertical integration into upgrading of titanium products, such as titanium slag, titanium metal, pigment production.
