Barry A. Wills and James Finch wrote a book "Mineral Processing Technology". They made a big mistake.

1. Barry A. Wills (England) and James Finch (Ph.D) wrote a book "Mineral Processing Technology". They made a big mistake.

They wrote that collectors can be Ionizing and Non-ionizing.  
This is not entirely correct.


Collectors can be Ionogenic and Non-ionogenic.

Ionogenic means that the reagent dissociates into ions when it enters the water (for example, anion and cation). Link

Ionization has a different physical meaning.

Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes.
For example, ionizing and non-ionizing radiations such as dental or non dental radiographies, mobile phone, cordless phone and cathode ray tube (CRT) and those of non-exposed mothers.

2. They wrote "Oxyhidryl collectors can float Non-sulfide minerals". This is mistake.

Oxyhidryl collectors can float Non-sulfide minerals and Sulfide minerals too.
