What are polymers, biopolymers, natural polymers in flotation?

Many chemical companies try to implement polymers in flotation (natural polymers, biopolymers, etc.). This is a traditional flotation reagents for some ores. However, none of the companies could not provide a method for the use of polymers in the flotation of copper ores. This is due to the properties of polymers. Polymers are the conditioners of pulp. For one and the same mineral under different conditions, the polymer may be a depressant or an activator.         

You can find:

1.1. Which reagents include polymers?                                                           
1.2. What are called as “anionic biopolymers” and why?                                   
1.3. Which minerals can be depressed by polymers very easily, and which minerals can not be depressed?                                                                                                    
1.4. In what sequence the polymers depress the minerals?                                
1.5. Which mechanisms of polymer fixing there are?
