<p>Ash is removed from fibrous stock suspensions when processing waste- paper, in particular following a flotation process carried out to remove printing inks with the aid of chemicals by separating the stock suspension in a sorting strainer, the ash and a short-fibre portion passing through the strainer, after which separation into ash and fibres which can be used again is effected, while the pulp stock remaining in front of the sorting strainer is conducted away for further processing.</p> |
