World metals production
gold production
This graph charts my estimates of annual gold production since 1900. The earlier (pre 1990) data were estimated every 5 years and the recent data annually. Annual production of gold has increased over 6 fold since 1900 and doubled since 1970.
2018 Update: Record high production of gold in 2017 per forecast. Future forecast higher that previous forecast.

steel production
This graph charts estimates of annual world production since 1960. The pre 1995 data were estimated every 5 years and the recent data annually. Annual production of crude steel has tripled since 1960. It is noteworthy how much more steel iis being produced each year in the 21st century as compared to the 20th century.
2018 Update: Record high production in 2017 right on forecast.

tin production
The above chart estimates total annual world production of tin. Reportedly tin is used in solder and is important in production of tablet computers and smart-phones. The chart shows estimated 5-year averages from 1960 through 2010 followed by annual estimates. Tin production was fairly flat 1960 to 1990, fell somewhat to 2010, but subsequently has erratically risen some 50% above 1960 levels.
June 2018 Update: Model revised based on more reliable data set. Forecast now shows increasing production levels, whereas last year's forecast was for slow falling production. 2017 production similar to that for 2016.

titanium production
Titanium is a low density, high strength and corrosion resistant metal. Titanium oxide, usually called titanium white, is a white pigment with aside range of applications from paint to food & plastics colouring. Both products have important economic benefit but I have only charted the metal, commonly referred to as titanium sponge.
June 2018 Update: World production still sideways. Forecast still optimistic.

NOTE: This section is expected to be expanded later this year. So far just these 4 metals have been evaluated as a pilot study.
