(a)Producing non-ferrous metals from ore, concentrates or secondary raw materials by metallurgical, chemical or electrolytic activities and in this paragraph “secondary raw materials” include scrap and other waste,
(b)Melting, including making alloys, of non-ferrous metals, including recovered products, and the operation of non-ferrous metal foundries in an installation with a melting capacity exceeding—
(i)4 tonnes per day for lead or cadmium, or
(ii)20 tonnes per day for all other metals in aggregate.
(c)Producing, melting or recovering (whether by chemical means or by electrolysis or by the use of heat) cadmium or mercury or any alloy containing more than 0.05 per cent by weight of either of those metals or of both of those metals in aggregate,
(d)Unless described elsewhere in this Section, melting (including making alloys, of non-ferrous metals, including recovered products), refining and foundry casting in a furnace, bath or other holding vessel which has a design holding capacity of 5 tonnes or more.
(a)The melting, including making alloys, of non ferrous metals, including recovered products, refining, foundry casting, etc. in an installation which has a design holding capacity of less than 5 tonnes, other than in respect of an activity—
(i)described in Part A, or
(ii)carried out in respect of tin, or an alloy which in molten form contains 50 per cent or more by weight of tin,
(b)The separation of copper, aluminium, magnesium or zinc from mixed scrap by differential heating,
(c)The heating in a furnace or any other application of any non-ferrous metal or non-ferrous metal alloy for the purpose of removing grease, oil or any other non-metallic contaminant, including such operations as the removal by heat of plastic or rubber covering from scrap cable if not related to another activity described in this Part; but an activity does not fall within this paragraph if—
(i)it involves the use of one or more furnaces or other appliances the primary combustion chambers of which have in aggregate a rated thermal input of less than 0.2 megawatts, and
(ii)it does not involve the removal by heat of plastic or rubber covering from scrap cable or of any asbestos contaminant;
(d)Melting zinc or a zinc alloy in conjunction with a galvanising activity at a rate not exceeding 20 tonnes per day,
(e)Melting zinc, aluminium or magnesium or an alloy of one or more of these metals in conjunction with a die-casting activity at a rate not exceeding 20 tonnes per day.
In this Part, “rated thermal input” has the same meaning as in Section 1.1.
In this Section, “non-ferrous metal alloy” and cognate expressions mean an alloy which is not a ferrous alloy as defined in Section 2.1.
Nothing in paragraph (c) or (d) of Part A or in Part B of this Section prescribes the activities of hand soldering, flow soldering or wave soldering.
