# Commission Implementing Decision (EU) 2016/1032 of 13 June 2016 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the non-ferrous metals industries (notified under document C(2016) 3563) (Text with EEA relevance), Division BAT 2

Extent: E+W+S+N.I.

In order to use energy efficiently, BAT is to use a combination of the techniques given below.
Technique
Applicability
a
Energy efficiency management system (e.g. ISO 50001)
Generally applicable
b
Regenerative or recuperative burners
Generally applicable
c
Heat recovery (e.g. steam, hot water, hot air) from waste process heat
Only applicable for pyrometallurgical processes
d
Regenerative thermal oxidiser
Only applicable when the abatement of a combustible pollutant is required
e
Preheat the furnace charge, combustion air or fuel using the heat recovered from hot gases from the melting stage
Only applicable for roasting or smelting of sulphide ore/concentrate and for other pyrometallurgical processes
f
Raise the temperature of the leaching liquors using steam or hot water from waste heat recovery
Only applicable for alumina or hydrometallurgical processes
g
Use hot gases from the launder as preheated combustion air
Only applicable for pyrometallurgical processes
h
Use oxygen-enriched air or pure oxygen in the burners to reduce energy consumption by allowing autogenous smelting or the complete combustion of carbonaceous material
Only applicable for furnaces that use raw materials containing sulphur or carbon
i
Dry concentrates and wet raw materials at low temperatures
Only applicable when drying is performed
j
Recover the chemical energy content of the carbon monoxide produced in an electric or shaft/blast furnace by using the exhaust gases as a fuel, after the removal of metals, in other production processes or to produce steam/hot water or electricity
Only applicable to exhaust gases with a CO content > 10 vol-%. Applicability is also influenced by the composition of the exhaust gas and the unavailability of a continuous flow (i.e. batch processes)
k
Recirculate the flue-gas back through an oxy-fuel burner to recover the energy contained in the total organic carbon present
Generally applicable
l
Suitable insulation for high temperature equipment such as steam and hot water pipes
Generally applicable
m
Use the heat generated from the production of sulphuric acid from sulphur dioxide to preheat gas directed to the sulphuric acid plant or to generate steam and/or hot water
Only applicable for non-ferrous metals plants including sulphuric acid or liquid SO2 production
n
Use high efficiency electric motors equipped with variable-frequency drive, for equipment such as fans
Generally applicable
o
Use control systems that automatically activate the air extraction system or adjust the extraction rate depending on actual emissions
Generally applicable
