Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10086-2 was prepared by Technical Committee ISO/TC 27, Solid mineral fuels, Subcommittee SC 1,
Coal preparation: Terminology and performance.
ISO 10086 consists of the following parts, under the general title Coal — Methods for evaluating flocculants
for use in coal preparation:
— Part 1: Basic parameters

Part 2:
Flocculants as filter aids in rotary vacuum filtration systems
1 Scope
This part of ISO 10086 specifies a method for the comparative evaluation of the performance of flocculants
used as filter aids for rotary vacuum filtration applications on a given slurry.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 10086-1:2000, Coal — Methods for evaluating flocculants for use in coal preparation — Part 1: Basic
parameters
3 Principle
The performance of different flocculants on a given slurry is determined by measuring the cake yield and
moisture content.
A flocculant solution is added to an aliquot of slurry in a beaker. A filter leaf is then applied to the flocculated
sample and the cake thus produced on the apparatus is weighed wet, dried and reweighed. A measure of the
efficiency of the flocculant is obtained from the cake yield and moisture content.
4 Apparatus
Ordinary laboratory apparatus and the following.
NOTE The apparatus is generally arranged as shown in Figure 1.
4.1 Laboratory vacuum pump or piped vacuum system, capable of producing a vacuum better than that
proposed for the plant equipment.
4.2 Vacuum gauge
4.3 Two-way valves, of at least 2 mm to 3 mm bore, manufactured in glass or plastics.
4.4 Buchner flask, with a minimum volume of 1 L.

Figure 4.
4.6 Vacuum tubing and glass/plastics tubing
4.7 Stirrers, motorized variable-speed stirrers, capable of speeds up to 1 000 r/min, one for flocculant
preparation and one for sample homogenization.
4.8 Syringes, having capacities of 1 ml, 2 ml, 5 ml, 10 ml and 50 ml.

5.1 Slurry
The slurry for evaluation shall be collected and divided by the method described in ISO 10086-1. The contents
of each test cylinder shall then be poured into an 800 ml beaker for evaluation.
5.2 Water
The water used for the preparation of flocculant solutions shall be collected by the method described in
ISO 10086-1.
6 Sampling
The flocculant samples should be collected according to the recommendations described in ISO 10086-1.
