  A method of treating pigments to impart to them improved properties including both hydrophobic and organophilic properties, which comprises forming in an aqueous medium a dispersion of the pigment to be treated and of at least one salt selected from the group consisting of alkali metal salts of higher fatty acids, resin acids, and naphthenic acids, said salt being dispersed in the medium in a quantity of from 0.1% to 5.0% based on the dry weight of the pigment and sufiicient to impart both hydrophobic and 'organophilic properties to the pigment,limestone crushing equipment then incorporating into said dispersion a solution of at least one metal salt selected from the group consisting of Water soluble salts of aluminum, magnesium, zinc, titanium, zirconium, tin, antimony, lead and rare earth metals, in an amount providing between 0.2% and 10% of said metal salt, based on the dry weight of the pigment, and suflicient to enhance surface properties of the pigment, and thereafter separating the pigment from said medium to obtain a product possessing said improved properties.
  
  A method of treating pigments to impart to them improved properties including both hydrophobic and organophilic properties, which comprises forming in an aqueous medium a dispersion of the pigment to be treated and of an organic substance having a non-polar hydrophobic radical carrying a polar substituent, said substance being selected from the group consisting of monoand di-substituted polysiloxanes and alkali metal salts of higher fatty acids,ore processing equipment resinic acids and naphthenic acids and mixtures thereof, said substance being dispersed in the medium in a quantity between 015 and 2% of the weight of the pigment, then incorporating into said dispersion a solution of at least one metal salt selected from the group consisting of water soluble salts of aluminum, magnesium, zinc, titanium, zirconium, tin, antimony, lead and rare earth metals, in an amount providing a quantity of said salt between 0.5 and 3% of the Weight of the pigment, and thereafter separating the pigment from said medium to obtain a product possessing said improved properties.
  
  6. A method of treating pigments to impart to them improved properties including both hydrophobic and organophilic properties, which comprises forming in an alkaline aqueous medium a dispersion of the pigment to be treated and of an organic substance having a non-polar hydrophobic radical carrying a polar substituent, said substance being selected from the group consisting of monoand di-substituted polysiloxanes and alkali metal salts of higher fatty acids, resinic acids and naphthenic acids and mixtures thereof, said substance being dispersed in the medium in a quantity between 0.5 and 2% of the weight of the pigment, then incorporating into said dispersion a solution of at least one metal salt selected from the group consisting of water soluble salts of aluminum, magnesium, zinc, titanium, zirconium, tin, antimony, lead and rare earth metals, in an amount providing a quantity of said salt between 0.5 and 3% of the weight of the pigment, neutralizing said medium, and thereafter separating the pigment from said medium to obtain a product possessing said improved properties.
