Inside the plant

There are two industrial routes to titanium dioxide: the sulphate process and the chloride process. TIKON uses the sulphate process, which starts from ilmenite and produces rutile pigment through acid digestion, hydrolysis, calcination and surface treatment.

What makes the site work is that almost nothing has to be brought in. Sulphuric acid, steam, process water and effluent treatment are all produced and handled here.

Raw material intake and storage. This is where the line begins — the ore is milled from here into the digestion stage.

The line

Step by step

Ilmenite arrives at one end of the site and finished pigment leaves at the other. Eight steps make the pigment; six more supply and clean up after them.

01Ilmenite warehouseRaw material intake and storage
02Ilmenite grindingThe ore is milled to the required fineness
03Acidolysis and hydrolysisThe ore is digested in sulphuric acid, then hydrolysed
04WashingImpurities, principally iron, are washed out
05CalcinationThe material is calcined to develop the rutile crystal structure
06GrindingThe calcined product is milled to pigment particle size
07Surface treatmentAlumina, zirconia and organic treatments are applied
08Finished products warehousePacking and dispatch

Quality and technology

Titanium dioxide is bought on numbers

Brightness, tint tone, dispersibility and residue decide whether a pigment works in a formulation, and those numbers have to be the same in every batch. Each batch is released against a defined internal standard, and a certificate of analysis is issued for every shipment.

Controlled parameters

  • TiO2 content
  • Rutile content
  • Brightness (L)
  • b value — tint tone
  • Tint reducing power (TCS)
  • Volatile matter at 105 °C
  • pH
  • Oil absorption
  • Residue on 325 mesh (45 µm)
  • Specific resistance
  • Dispersibility (Hegman)

Standards

Our coatings and plastics grades are produced to conform to ASTM D476 and BS EN ISO 591-1:2000 Type R2, and are listed under EINECS 236-675-5, CAS 13463-67-7, Colour Index 77891, Pigment White 6.

On the site

Raw material storage

Feedstock is held on site, so the acid plant and the pigment line are not waiting on deliveries.

Safety and environment

Everyone goes home

Our target is zero incidents and zero harm — to our employees, to our contractors and to the people who live around the plant. That target is only reachable if it is owned by everyone on site and visibly led from the top, and that is how we run it.

Closing the loop on site

A sulphate process plant is judged by what it does with what it does not sell. At TIKON, spent acid is concentrated and returned to the process rather than discharged, effluent is treated in our own facility on site, and heat from the process is recovered through the boiler system.

Our commitments

  • Prevent unplanned environmental impacts and minimise our environmental footprint
  • Operate within the environmental permits and standards that apply to our site
  • Keep improving process efficiency, so that less input produces the same output
