How do manufacturing and producer service agglomerations …
Despite the growing body of literature on the influence of industrial agglomeration on urban innovation, no consensus has been reached on the mechanism of the spillover effect. This empirical study exploits heterogeneity in spillover effects between manufacturing and producer service agglomerations on urban innovation based on a …
Agglomeration technique improves heap leaching process
In the case of heap leaching, agglomeration relies on a binder (typically cement) and tumbling motion to cause coalescence, or the building of fines into larger particles. Agglomeration drums (sometimes referred to as ore drums or agglomerators) are the equipment of choice for agglomerating ore fines in preparation of heap leaching.
New wave of consolidation is expected in the cement industry
India accounts for around 8% of global cement production. The Adani Group's entry into the cement industry would spark a new round of consolidation, with corporations bidding for the almost 25 million tonne per year (MTPA) of stressed assets on the market. In addition, cement manufacturers' development plans might add another …
