Full title and description

ISO 10086-1:2019 — Coal — Methods for evaluating flocculants for use in coal preparation — Part 1: Basic parameters. This International Standard specifies laboratory methods for the comparative evaluation of flocculant performance in slurries, including measurement of initial settling velocity, sediment volume after compaction/consolidation, and clarity of the supernatant liquid.

Abstract

This document provides a standardized procedure to compare the effectiveness of flocculants used in coal preparation operations. Tests cover preparation of flocculant solutions, sample preparation, determination of settling behaviour and sediment characteristics, clarity measurement of supernatant, calculation and reporting of results, and repeatability requirements. Annexes include a worked example and data recording sheets.

Scope

Specifies a method for the comparative evaluation of the performance of flocculants for clarification, thickening and sedimentation applications on a given coal slurry. It covers test principle, apparatus and materials, sampling, preparation of test solutions (powder and liquid flocculants), procedures to determine settling rates and full settling curves, measurement of sediment height and supernatant clarity, calculation of dosage and results, repeatability and required test reporting. It is intended for laboratory-scale evaluation rather than full-scale plant qualification.

Key topics and requirements

• Preparation and handling of slurry and flocculant solutions (powder and liquid forms).
• Determination of initial free settling velocity and full settling curve for comparative evaluation.
• Measurement of sediment volume after compaction/consolidation and clarity of supernatant liquid.
• Calculation of flocculant dosage rate and reporting of results with repeatability criteria.
• Specified apparatus, sampling procedures and test-report format; includes worked example and data recording sheets (informative annexes).

Typical use and users

Used by coal preparation laboratories, process engineers in mining and coal-processing plants, flocculant manufacturers and suppliers, independent test houses, and R&D groups evaluating flocculant performance for clarification, thickening and filtration-preparation tasks.

Related standards

ISO 10086 is a multi-part series. Part 1 is the basic parameters standard (this document). Part 2 (Flocculants as filter aids in rotary vacuum filtration systems) exists as earlier editions (ISO 10086-2:2004) and has been under revision / committee draft development in ISO/TC 27/SC 1. Users should consult the series for complementary test methods addressing filtration-specific evaluations.

FAQ

Q: What is this standard?

A: ISO 10086-1:2019 is an International Standard that defines laboratory methods to evaluate and compare the performance of flocculants used in coal preparation (basic parameters such as settling rate, sediment volume and supernatant clarity).

Q: What does it cover?

A: It covers test principle, required apparatus and materials, sample and solution preparation, procedures for determining settling characteristics and supernatant clarity, calculations (including dosage), repeatability, and how to record and report results; includes informative annexes with worked example and data sheets.

Q: Who typically uses it?

A: Coal preparation laboratories, plant process engineers, flocculant suppliers, independent testing organisations and researchers evaluating flocculant options for clarification, thickening and filtration-preparation applications.

Q: Is it current or superseded?

A: ISO 10086-1:2019 is the current published version (Edition 2, published July 2019) and the ISO record indicates it was confirmed on review and remains current. It replaced the earlier ISO 10086-1:2000.

Q: Is it part of a series?

A: Yes — ISO 10086 is a multi-part series addressing methods for evaluating flocculants in coal preparation. Part 2 (filtration-specific methods) has an earlier 2004 edition and has been subject to revision activity; consult ISO/TC 27/SC 1 outputs for the current status of other parts.
