Abstract
This invention provides a surprisingly efficacious combination useful for inhibiting microorganism growth, particularly in aqueous slurries containing mineral ore. In particular embodiments, the invention provides an antimicrobial composition comprising 1-(3-chloroallyl)-3,5,7 triaza-1-azoniaadamantane chloride and 2-bromo-2-nitropropane-1,3-diol. The invention also provides a method for inhibiting microbial growth in an aqueus mineral or ore slurry, e.g. a kaolin slurry. The method includes the step of adding to the slurry a microbiocidal composition of 1-(3-chloroallyl)-3,5,7 triaza-1-azoniaadamantane chloride and 2-bromo-2-nitropropane-1,3-diol.
