Hindustan Zinc Limited recently announced its production numbers for the second quarter and half year ended September 30, 2022.
The company in an official release stated that it saw highest-ever second quarter mined metal production at 255kt, up 3% YoY which was driven by better grades and improved mill recoveries.
Refined metal production stood at 246kt, which was an increase of 18% YoY with improved smelter performance, better mined metal availability and base impact due to extended maintenance shutdown in the same period last year.
However, refined metal was lower by 6% QoQ because of lower roaster availability due to breakdown of an acid storage tank at Chanderiya plant in 2QFY23 and time taken in ramp up of production post maintenance.
Integrated zinc production was at 189kt, up 16% YoY and down 8% QoQ. Refined lead production was 57kt up 21% YoY and 5% QoQ. Saleable silver production was 6.2 moz, up 28% YoY and 10% QoQ in line with lead metal production and WIP liquidation.
First half mined metal production at 507kt was 8% higher YoY, on account of increase in ore production, further supported by better grades & improved operational efficiency.
First half refined metal production at 506kt, was up 13% YoY, resulting from consistent mined metal flow from mines and better plant availability partly offset by acid storage tank breakdown at Chanderiya plant in 2QFY23.
1HFY23 integrated zinc production was at 395kt, up 13% YoY and refined lead production was at 110kt, up 16% YoY.
Saleable silver production was 11.9 moz, up 19% YoY in-line with lead metal production.
