| 20100278890 | Use of Lignosulfonates in Suspo-emulsions for Producing Pesticide Compositions - Disclosed are compositions and methods related to powder and granular concentrate pesticide formulations. As disclosed, suspo-emulsions comprising pesticide actives may be prepared using a high purity, high molecular weight lignosulfonate as a stabilizer. The resulting suspo-emulsions may then be dried to obtain a powder or granular concentrate where the high molecular weight lignosulfonate acts as a solid matrix for the pesticide actives. The powder or granular concentrate formulations thus formed have high loading rates, good storage properties and are easily reconstituted when added to water. | 11-04-2010 |
| 20100233050 | Hardwood Lignosulfonates for Separating Gangue Materials From Metallic Sulfide Ores - Disclosed are compositions and methods for separating gangue material from metallic sulfide ores. The compositions typically include a lignosulfonate and do not include a cyanide salt. Suitable lignosulfonates may include lignosulfonates, for example hardwood lignosulfonate having a weight average molecular weight of about 3 kDa to about 12 kDa and having a relatively low sulfur content and a relatively low sulfonate content. | 09-16-2010 |
