Personal Protection – Always wear protective gear when working with Xanthates. Gear should include long sleeved clothing, safety goggles, a respirator with high-grade particulate matter filters, and gloves, boots and apron that are made of Neoprene, polyvinyl, butyl rubber or nitrile rubber, or Dupont Tyvek® suits.
It is critical to keep Xanthate pellets away from moisture, humidity and sparks during storage. It can also form flammable gases as it decomposes.
SNF Mining Xanthate is hermetically sealed, unlike other manufacturers’ products. Under optimum conditions, Xanthate remains stable for up to one year when stored sealed under cool and dry conditions. Avoid high temperatures, ignition sources, moisture, and strong acids and oxidizing agents. Carbon disulfide, isopropyl alcohol, and carbon monoxide are Hazardous substances that may form under fire conditions. Tank covers, openings and overflow vents should remain closed or should be vented to a treatment area. Precautions should be taken to avoid static electricity discharge. Storage areas should be monitored frequently for explosive gasses.
As Xanthate decomposes, the products it gives off include alcohols, carbon disulfide (CS2), and carbon monoxide.
In rats, the lethal dose is 1,000 – 2,000 mg/kg for a 10% solution. It can cause mild to severe irritation to the skin and eyes.
Case Study – In the following case study, exposure to Xanthate through skin contamination resulted in TTCA in the urine, and within 20 hours, some of the following symptoms were present: gastric burning, abdominal tightness, fainting, nausea, vomiting, fatigue, and headache.

Always wear protective gear when working with Xanthates. Gear should include long sleeved clothing, safety goggles, a respirator with high-grade particulate matter filters, and gloves, boots and apron that are made of Neoprene, polyvinyl, butyl rubber or nitrile rubber, or Dupont Tyvek® suits.
When mixing Xanthates, adding water first results in a concentration of 10 parts per million above the solution. Adding Xanthate first will result in 60 parts per million, above the solution. It is recommended to add water first.
Physical Contact – Skin – If contact with the skin has occurred, remove contaminated clothing immediately and wash skin thoroughly with soap and lots of water.
Physical Contact – Eyes – If contact with eyes has been made, rinse eyes thoroughly with plenty of water for at least 15 minutes and consult a physician.
Inhalation – If Xanthate or carbon disulfide has been inhaled, move the victim to fresh air immediately.
Ingestion – If Xanthate has been ingested, do not induce vomiting. Seek medical attention immediately.
When fighting a fire involving Xanthates, wear full protective gear for the body and eyes, and use a NIOSH approved, positive pressure, self-contained respirator. Use carbon dioxide, dry chemical, or foam to extinguish. Avoid using water if dry xanthates nearby can get wet. Avoid contact with dust, mist, and liquids, and keep all personnel removed and upwind of fire.
Xanthate should be disposed of only in accordance with regulations. Do not contaminate any lakes, streams, ponds, groundwater or soil. Containers should be completely emptied and disposed of in accordance with regulations.
This product is regulated as a dangerous good as defined by the International Maritime Dangerous Goods code for marine transport.
