Cobalt Waste
London Chemicals is an international distributor and specialise in services relating to Cobalt waste. We specialise in distribution and recycling services including cobalt metal and cobalt salts and our business encompasses a range of metallurgical and chemical raw materials, by-products, residues and spent catalysts for downstream use, reclamation and recycling. LCR creates elegant recycling loops – buying back fully processed chemicals and metals from companies we have supplied with secondaries. These are resold to industry worldwide to restart the loop.
Cobalt(II) oxide or cobalt monoxide is an inorganic compound that appears as olive-green to red crystals, or as a greyish or black powder. It is used extensively in the ceramics industry as an additive to create blue coloured glazes and enamels as well as in the chemical industry for producing cobalt(II) salts.
CoO crystals adopt the periclase (rock salt) structure with a lattice constant of 4.2615 Å.
It is antiferromagnetic below 16 °C.
Preparation
Cobalt(II,III) oxide decomposes to cobalt(II) oxide at 950 °C:
- 2 Co3O4 → 6 CoO + O2
Though commercially available, cobalt(II) oxide may be prepared in the laboratory by electrolyzing a solution of cobalt(II) chloride.
CoCl2 + H2O → CoO + H2 + Cl2
It may also be prepared by precipitating the hydroxide, followed by thermal dehydration:
- CoX + 2 KOH → Co(OH)2 + K2X
- Co(OH)2 → CoO + H2O
Reactions
As can be expected, cobalt(II) oxide reacts with mineral acids to form the corresponding cobalt salts:
- CoO + 2 HX → CoX2 + H2O
Applications
Cobalt(II) oxide has for centuries used as a colouring agent on kiln fired pottery. The additive provides a deep shade of blue named cobalt blue. The band gap (CoO) is around 2.4 eV. It also is used in cobalt blue glass.
Customised Solutions
The absence of comprehensive recycling facilities capable of handling all types and forms of spent catalyst and other secondary raw materials makes it difficult for the generator to find the appropriate recycling outlet. In addition, environmental legislation and transport regulations can be complicated and often vary from country to country. It is a minefield for the uninitiated.
We provide customised recycling solutions to the generators of spent catalyst arising from Oil Refining, Petrochemical, Syngas and Fertilizer Industries.
It is our aim to provide commercially competitive recycling options with an emphasis on environmentally sound management.
Although it is the obligation of the generators of the spent catalyst to classify the material, our knowledgeable and friendly staff can offer advice and assistance with regards to:
- Packaging Requirements – Whether material should be shipped in bulk, UN/DOT approved drums, catalyst bins or supersacks.
- Transport Regulations – Our staff are fully conversant with the latest transport regulations and regularly attend courses and updates covering the transport of dangerous goods by land (ADR), sea (IMDG) and air (IATA) as well as 49CFR for movements within the USA.
- Applicable Environmental Regulations – We have years of experience in transboundary movement of hazardous waste, non-hazardous waste, hazardous and non-hazardous metals and concentrates.
A network of agents and associates around the globe together with long term relationships with fully licenced, ISO9001 and ISO14001 certified recycling facilities, enable us to provide the most suitable, commercially competitive options for each generator.
Site visits / environmental audits are available where required.
Many of the recovered metals are returned to the industry in the form of high purity raw materials thus closing the recycling loop.
Please do not hesitate to contact us to discuss your Recycle Spent Catalysts options.
Recycled Spent Catalysts
The spent catalysts are recycled and used to produce high-quality metal salts for final applications including new catalyst manufacture, pigments and CO2 removal processes.
LCR also handles many types and forms of other non-ferrous secondaries including, fines, slags, residues, sludges, ashes etc. containing: Co, Cu, Mo, Ni, V, W, Zn.
LCR’s services include advice on packaging and current environmental legislation, transportation according to the latest regulations, the arrangement of weighing and sampling, recycling at fully approved facilities and issuance of Certificates of Recycling/Consumption where required.
