A mineral ionizing device (10) consisting of a container (20) filled with water and containing a solid-mineral, cylindrical first electrode (50), a second electrode (58) coaxially located within the first electrode (50), a vibration unit (100) which produces a vibration within the container (20), a
A mineral ionizing device (10) consisting of a container (20) filled with water and containing a solid-mineral, cylindrical first electrode (50), a second electrode (58) coaxially located within the first electrode (50), a vibration unit (100) which produces a vibration within the container (20), a set of protrusions (64) located on the surface of the second electrode (58) and a periodic current reversing unit (84) which applies a d-c current across the first and second electrodes (50,58). The combination of the vibration unit (100), the protrusions (64) and the current reversing unit (84) aids in releasing gaseous bubbles which form on the surface of the second electrode (58). The application of the d-c current causes the mineral in the first electrode (50) to release mineral ions into the water which results in the production of very clean mineral water.

The process according to claim 1, wherein said calcium carbonate is present in said pulp suspension as a filler and/or a pigment. 3. The process according to claim 2, wherein said carbon dioxide is introduced at a location physically close to the point of addition of calcium carbonate. 4. The process according to claim 1, wherein said calcium carbonate in said pulp suspension derives from recycled fibers or broke containing calcium carbonate as filler or pigment. 5. The process according to claim 1, wherein said carbon dioxide is introduced into a stream of pulp suspension. 6. The process according to claim 1, wherein said carbon dioxide is introduced into a stream of water which is then added to said pulp suspension. 7. The process according to claim 1, wherein said carbon dioxide or additional carbon dioxide is introduced into said calcium carbonate containing pulp suspension just prior to or in connection with an acidic process chemical being added to said pulp suspension. 8. The process according to claim 1, wherein said pH conditions comprise a pH of 7.5 to 7. 9. The process according to claim 1, wherein said carbon dioxide is used in an amount which causes a significant lowering of the pH of said pulp suspension. 10. The process according to claim 9, wherein said carbon dioxide is introduced in an amount sufficient for lowering the pH of said pulp suspension to a pH level of about 7.6 or lower. 11. The process according to claim 9, wherein the pH of said pulp suspension is adjusted with carbon dioxide to a pH of 5.5 to 7.6. 12. The process of claim 11, wherein said pH is adjusted to 6.5-7.5. 13. The process according to claim 1, wherein said pulp suspension is recycled pulp, chemical pulp or mechanical pulp. 14. The process according to claim 13, wherein said pulp suspension is recycled pulp containing a significant amount of calcium carbonate. 15. The process according to claim 14, wherein said carbon dioxide is introduced into a deinking plant for processing recycled fibers at an alkaline pH. 16. The process according to claim 14, wherein said carbon dioxide is introduced prior to and/or in connection with said calcium carbonate containing pulp suspension being diluted with water having a pH of 8 or lower. 17. The process according to claim 13, wherein said carbon dioxide is introduced prior to a dithionite bleaching of said calcium carbonate containing pulp suspension. 18. The process according claim 13, wherein said carbon dioxide is introduced just before said calcium carbonate containing recycled pulp enters a paper making process operating at a neutral or acidic pH. 19. The process according to claim 18, wherein said carbon dioxide is introduced in connection with pumping said calcium carbonate containing recycled pulp to a storage tank of a paper machine. 20. The process according claim 1, wherein said aqueous pulp suspension is a chemical or mechanical pulp or stock substantially devoid of calcium carbonate and said calcium carbonate comprises solid filler which is added into said pulp suspension in a paper making process. 21. The process according to claim 20, wherein said calcium carbonate is added in a stock preparation step, optionally prior to and/or in
